\head 1. Introduction
\endhead
%%
The purpose of these \GL\/ is to explain to authors the details of
electronic manuscript preparation and submission to the AMS and the
handling of these papers once they reach the AMS\null.  It is assumed that
the reader is familiar with \AmSTeX{} and has access to the items
listed in the \secref{References} section, especially \JoT\/ \cite{Joy}
and {\it \AmSTeX{} Version \rom{2.0} User's Guide} \cite{ATG}\null.
Both these \GL\/ and the accompanying examples have been created to
help avoid problems before they occur and minimize extra work for all
involved in the production of the paper.

Instructions for using specific macros will be given in appropriate
sections of these \GL.  Examples of macro use (input and output) can be
found in the sample papers that accompany these \GL.

The AMS book series that are published from author-prepared copy may
have additional requirements, which are not included here.
For specific instructions on preparing an \AmSTeX{} manuscript for
such a series, send an inquiry to the address given in the
\secref{How to submit a file} section.


\subhead Classes of manuscripts covered
\endsubhead
%%
These \GL{} include instructions for preparing both articles and monographs.
An article may be intended for either a journal or for a collection such
as the proceedings of a conference; where the requirements differ, the
differences are explained.  A separate section is devoted to monographs,
which differ substantially from articles in their requirements.
These \GL\/ do not include instructions for preparation of electronic
manuscripts for submission to either {\it Abstracts of Papers Presented to
the AMS\/} or {\it Mathematical Reviews}.  Instructions for {\it Abstracts\/}
can be requested from the Society's Publication Division; instructions for
{\it Mathematical Reviews\/} can be found on the reverse side of the
contents page of any MR issue.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\head 2. General guidelines
\endhead
%%
All manuscripts submitted to the AMS, whether in paper or electronic
form, should contain certain information.  When that
information is missing, extra time and effort are required to obtain it,
and this process may result in delays in publication.  The following
elements should be included with all manuscripts.
\roster
\item Identification of the series in which the work is to appear.
\item Title, including short form if necessary for running head.
\item Author name(s), including shortened form if necessary.
\item Address(es) of the author(s) where the research was performed,
   current address(es), and address(es) for electronic mail if available.
\item Subject classification(s) (primary and, if appropriate, secondary)
   according to the {\it Mathematical Reviews\/} Subject Classification.
\item Abstract (for a paper to be published in a journal).
\endroster
Detailed instructions are given later for the form to be used for
particular elements, and a checklist is provided to assist authors.

Some basic principles are important for effective handling of electronic
submissions in production.  Authors should keep these in mind when
preparing their files.
\roster
\item Use the \AmSTeX{} preprint format unless you have been provided
   with a specific alternative for a particular publication.
\item \AmSTeX{} contains tags to identify all the important features of
   mathematical papers and monographs; use them, not tags you define
   yourself.
\item Do not use \TeX{} coding to control line and page breaks. Lines
   and pages will break differently in the published paper than they
   did in the file you submit.  This is because AMS publications are set
   in a font (Times Roman) that prints slightly larger and has a different
   appearance than the font available for general \TeX{} distribution
   (Computer Modern).  If \TeX{} coding were inserted by authors for page
   and line breaks, it would have to be removed for production.
   That work could offset any time saved by not having to keyboard the
   manuscript and errors could be introduced.
\item Macro definitions for frequently occurring phrases or mathematical
   expressions should appear together at the beginning of the file,
   before the start of the text of the manuscript.  Once a macro is
   created for an expression, it should be used for every occurrence of
   that expression.
\item Do not redefine any plain \TeX{} or \AmSTeX{} control sequences.
\item Every file should be able to be processed independently; do not
   use ``input'' files, but instead include the contents of any such
   files in the main source file.
\item Use \TeX{} coding for special fonts (e.g., boldface or italic)
   only within the text of the manuscript; do not use such coding for
   any headings.
\item Proofread your manuscript thoroughly and carefully.
\endroster


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\head 3. Top matter
\endhead
%%
The top matter associated with a paper includes everything that would
appear in a bibliographic reference to the paper, plus additional
information about the author(s), subject classifications, keywords,
and acknowledgments of support.  These elements should be supplied by
the author; they will be augmented during production by such things as
date received, the publication logo, the copyright notice, and starting
page number.  These instructions describe only the elements to be
provided by the author.


\subhead Summary of tags and elements
\endsubhead
%%
The list below includes all the top matter tags associated with the
preprint style defined for \AmSTeX{} Version~2.0.  This style was
designed to be compatible with all AMS journals and collections of
papers, and the tags provided are a superset of those required for
papers in any of those publications.  Requirements for monographs are
somewhat different and are described later.

The style of the typeset output is controlled by the preprint style.
Some of the top matter elements have a ``\ttcs{nofrills}'' option, to
permit an author to change the preprint style's default values.  For
example, the tag \ttcs{keywords} will print the phrase ``{\it Key
words and phrases.}''\ just before the key words that are input by the
author.  The author would use the \ttcs{nofrills} option
if he does not want a phrase to precede the key words or if he wants a 
different phrase.

Whether or not a particular tag is required and whether the
\ttcs{nofrills} option is available are indicated in the list below.

Every file must begin with the statement \ttcs{input amstex}.  This
must be followed immediately by an appropriate \ttcs{documentstyle}
line.  The contents of next section, the preamble, are described in
more detail following the list of top matter tags.

\endexample

Note that nearly all the top matter tags are paired, requiring both a
beginning and an ending tag.  (The few exceptions are associated more
with formatting than with content.)  If any \ttcs{end...} tag is
omitted, an error message will appear at \ttcs{endtopmatter}, if not
before.  If the forgotten \ttcs{end...} tag is one for which the
\ttcs{nofrills} option has been used, the error message will be
``{\tt !~Paragraph ended before \ttcs{next\@} was complete}.''  
If the \ttcs{endtopmatter} tag is omitted, none of the top matter
material will print.


\subhead The preamble\endsubhead
%%
The area between the \ttcs{documentstyle} line and the
\ttcs{topmatter} line is referred to as the ``preamble.''  If any new
control sequences are used in the paper, their definitions should be
placed in the preamble.  Similarly, instructions to access fonts that
are not already loaded in \AmSTeX{}, such as bold symbols (see
\cite{ATG\rm, pp.\ 14--15}), belong here.  By placing these
general instructions at the very beginning of a paper, they will be
available throughout the entire paper.  In addition, this placement
will also make it easier for the production staff to find and check
them for compatibility when the paper is combined with others to
produce the complete publication.

When defining new control sequences, always use \ttcs{define}; this
will let you know if the name you have chosen has already been used.
Do not redefine any plain \TeX{} or \AmSTeX{} command, as this could
cause problems in AMS production.
New definitions may be used to provide shorthand forms for text or
mathematical expressions that are used frequently.  They should not
include any formatting commands.


\subhead Title (required)\endsubhead
%%
The title should always be entered in the standard AMS style, which is
{\bf caps and lowercase}.  Major words should begin with capital letters,
and lowercase should be used elsewhere.  This is true even if the
publication in which the paper appears has a style that requires all caps;
that form will be generated automatically when the paper is processed
at the AMS\null.  A multi-line title may be left for \TeX{} to break,
or a desired break may be indicated by the author with \ttcs{\\}.

Unless the title is very short, the author should provide a form of
the title suitable for use in running heads.  This should be entered
{\bf in all caps} with the tag \ttcs{rightheadtext\{...\}}.


\subhead Author information (required)\endsubhead
%%
The name(s) of the author(s) should be entered in {\bf caps and lowercase}
using the tag \ttcs{author}.  All caps will be provided automatically if
that is the publication style.  If the information is more than one line
long, a line break may be indicated with \ttcs{\\}.

If the author name(s) cannot fit in the space available for the running
head, a shortened form should be entered {\bf in all caps} with the tag
\ttcs{leftheadtext\{...\}}.  Acceptable shortened forms use initials for
all but the surname(s), or substitute ``et al.''\ for all names after
the first if there are more than two authors.

For each author one or more addresses should be input.  The address
where the research was carried out should be tagged as
\ttcs{address ...\\endaddress}.  If the current address is different
from the research address, the current address should be given next,
tagged as \ttcs{curraddr ...\\endcurraddr}.  Following these addresses,
an address for electronic mail should be given, if one exists, with
\ttcs{email ...\\endemail}.  Regular, current, and e-mail addresses must
be grouped in that order by author; a current address or an e-mail
address that is not preceded by an ordinary \ttcs{address} will not
print.

The tag \ttcs{curraddr} was not defined in the version~2.0 preprint style;
it was added in version~2.1.  If you are using version~2.0, include the
following definition in the preamble of your file to make \ttcs{curraddr}
available; this definition will be replaced in production.
\beginexample
\\def\\curraddr\#1\\endcurraddr\{\\address
\ \ \ \{\\it Current address\\/\}: \#1\\endaddress\}
\endexample

Note that no abbreviations are to be used in addresses, and complete
addresses for each author should be entered in the order that names appear
on the title page.  (Examples are given in the sample article that
accompanies these \GL.)  Addresses are considered part of the top matter,
but in AMS publications they are ordinarily printed at the end
of the paper, following the bibliography.  Suitable labels will indicate
the current and e-mail addresses, typically ``{\it Current address\/}:''
and ``{\it E-mail\/}:'' respectively.

The AMS now uses full addresses in all its publications, so
\ttcs{affil} is no longer used.


\subhead Dedication\endsubhead
%%
The tag \ttcs{dedicatory} is to be used for such things as
``Dedicated to Professor X on the occasion of his eightieth birthday.''
A dedication will appear in italics, before the abstract.  If this is
longer than one line, a break may be indicated by \ttcs{\\}.


\subhead Acknowledgments of support and other first-page footnotes
\endsubhead
%%
\ttcs{thanks} is used for footnotes that appear on the first page.
Unlike \ttcs{address} and \ttcs{email}, \ttcs{thanks} cannot appear
more than once in the top matter.  It is sometimes desirable, however,
to acknowledge support separately for separate authors of a joint
paper.  Since \ttcs{thanks} creates an unnumbered footnote, separate
acknowledgments should be made into separate paragraphs within the
footnote.
But this brings up a special problem: It's fairly easy to forget the
ending~{\tt\}} for a \ttcs{footnote}, so an error-detecting mechanism
built into \TeX{} looks for the end of a paragraph within a footnote, and
if it sees one, assumes that you've forgotten the~{\tt\}} and issues an
error message.  In order to end a paragraph without setting off the
error-detector, you must use \ttcs{endgraf} instead of a blank line or
\ttcs{par}.

Papers published in proceedings of conferences are often abstracts or
preliminary versions.  In such a case, include as a separate paragraph
within \ttcs{thanks} the statement ``The final [detailed] version of this
paper will be [has been] submitted for publication elsewhere.''  Papers
that are to be considered for review by {\it Mathematical Reviews\/}
should include the following statement: ``This paper is in final form
and no version of it will be submitted for publication elsewhere.''


\subhead Translator\endsubhead
%%
This element is relevant only to translated papers, and should, if it
appears, be the name of the translator.  This information will ordinarily
be printed at the end of the paper, as ``Translated by'' followed by the
translator's name.


\subhead Subject information (required)\endsubhead
%%
Subject classifications and keywords, like acknowledgments, are part
of the top matter and will appear as footnotes at the bottom of the
first page.  Subject classifications are {\bf required}.

Subject classifications may be primary (the major topic(s) of the paper)
or secondary (subject areas covered by ancillary results, motivation
or origin of problems discussed, intended or potential field of
application, or other significant aspects worthy of notice).  One
primary subject classification is required; additional primaries and
secondaries are optional.

These classifications are entered as
\beginexample{}
\\subjclass Primary \<primary classifications>;
\ Secondary \<secondary classifications> \\endsubjclass
\endexample
See the sample article that accompanies these \GL\/ for examples.

To determine the classifications, use the 1980 Mathematics Subject
Classification (1985 Revision) that appears in annual indexes of
{\it Mathematical Reviews\/} beginning in 1984.  (The two-digit code
from the Contents of MR is {\bf not} sufficient.)

Keywords are not required but may be provided by an author if desired.
They should be tagged as \ttcs{keywords ...\\endkeywords}.


\subhead Abstract (required)\endsubhead
%%
The abstract is input with \ttcs{abstract...\\endabstract}.  It may
comprise multiple paragraphs and include displayed material if
appropriate.  The length of the abstract depends primarily on the
length of the paper itself and on the difficulty of summarizing the
material, but an upper limit of about 150 words for short papers and
300 words for long papers is suggested.

Though the styles of various publications may differ somewhat, the
preprint style is typical.  The abstract will be set in eight point
type on a narrower measure than the body of the paper, centered on the
first page, with the label ``{\smc Abstract.}''\ provided automatically
as the first word of the first paragraph.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\head 4. Document body
\endhead
%%
There are two essentially different types of documents that may appear
in AMS publications, individual papers (in journals or collections of
proceedings) and monographs.  This section contains descriptions of
those elements that are common to both types of documents.


\subhead Headings\endsubhead
%%
Four levels of headings are provided to permit logical sectioning of a
manuscript.  These headings are applicable to papers and within chapters
of a monograph.

\beginexample{}
\\specialhead...\\endspecialhead
\\head...\\endhead
\\subhead...\\endsubhead
\\subsubhead...\\endsubsubhead
\endexample

\ttcs{specialhead} is for long articles that need extra divisions
(e.g., chapters, parts) at a level above the \ttcs{head} level.  In the
preprint style \ttcs{specialhead} uses boldface type and is set
flush to the left margin on a line by itself.
\ttcs{head} is small caps, centered; \ttcs{subhead} is boldface,
flush to the left margin, and run in with the following text; and
\ttcs{subsubhead} is italic, indented as for an ordinary paragraph, and
run into the text.  The style shown in these \GL\/ is that of the
preprint style, which is based on the style of the \JAMS; \ttcs{head} is
the highest level used in this document.

Explicit line breaks are obtained by \ttcs{\\} in a \ttcs{head} or a
\ttcs{specialhead}, but for \ttcs{subhead} and \ttcs{subsubhead},
which are part of their paragraph, just use \ttcs{linebreak} as you
would in normal paragraphed text.  Do not leave a blank line after any
heading.  If you prefer the appearance of a blank line (so that the file
is easier to read), a comment line (containing only a {\tt\%}) is a good
substitute.

If you are preparing a monograph, there are some additional considerations
relevant to headings.
For details, see the \secref{Monograph formatting} section.


\subhead Mathematical text\endsubhead
%%
For instructions on preparing mathematical text, the author is referred to
\JoT\/ \cite{Joy} and the sample article which accompanies these \GL.

Care should be taken to use math mode for {\it all\/} mathematical
expressions, no matter how short or insignificant.  For example, in the
phrase ``a group of class 2,'' the ``2'' should be treated as mathematical
text and placed between dollar signs: {\tt \$2\$}.  One reason for this is
that numerals are always roman in mathematical expressions, whereas in
ordinary text environments \TeX{} sets them in the style of the surrounding
text; see also the \secref{Roman type} section below.

The sample paper that accompanies these \GL\/ contains some mathematical
examples, intended to illustrate the recommended manner of input.  The
input file for the sample paper should be examined to clarify the details
of input conventions.


\subhead Lists\endsubhead
%%
Lists are produced by \ttcs{roster...\\endroster}, with the individual
items tagged by \ttcs{item}.  Most details of input are given in \JoT\/
\cite{Joy\rm, Chapter 19, \bf Roster}.  In addition to what is described
there, the amount of indentation can be adjusted to accommodate wide item
numbers.  Just before beginning the \ttcs{roster}, type, for example,
\ttcs{widestnumber\\item\{(viii)\}}.  This adjustment is temporary;
the default will be reinstated by \ttcs{endroster}.

For an example of the use of \ttcs{roster}, see the Lemma in the sample
paper.


\subhead Theorems, lemmas, and other proclamations\endsubhead
%%
There are several varieties of proclamations and related objects.
All have the same generic form:
\beginexample{}
\\\<tag>\{\<heading text>\}
\ \<general text>
\\end\<tag>
\endexample
\noindent
The following list gives the specific tags recognized by the preprint
style, along with the types of heading text for which each is to be used.
\beginexample{\exboxwidth=1.85in}
\exbox{}{\\proclaim ...} Theorem, Lemma, Corollary, Proposition,
\exbox{}{\ \ \ \ \\endproclaim} Criterion, Algorithm, Condition
\exbox{}{\\demo ... \\enddemo} Proof
\exbox{}{\\remark ...} Remark, Note, Notation, Claim, Summary,
\exbox{}{\ \ \ \ \\endremark} Acknowledgment, Case, Conclusion
\exbox{}{\\definition ... \\enddefinition}\newline %
  Definition, Conjecture, Problem
\exbox{}{\\example ... \\endexample} Example
\endexample

Note that all these objects should have both their beginnings and ends
marked in the file.  The \ttcs{proclaim} text will be set in ``slanted''
type by the preprint style.  The text for all other classes of
proclamations will be roman.  ({\sl Slanted type is essentially the same
as roman, but the letters are slightly skewed;} {\it letters in italic
type are drawn in a different style.})  In the absence of a matching
\ttcs{endproclaim}, slanted type would continue beyond where it should;
for this reason, the tags for all other classes of proclamations include
a check for a ``runaway'' \ttcs{proclaim} and will report it if one is
detected.

Punctuation and spacing are provided automatically for the heading
text.  If something different is required, \ttcs{nofrills} can be used
with any of these tags.


\subhead Roman type\endsubhead
%%
Numbers, punctuation, (parentheses), [brackets], \{braces\}, and
symbols used as labels should always be set in roman type.  This is
true even within the statement of a theorem, which is set in slanted
type by the preprint style.

Be careful to distinguish between roman elements that are mathematical
in nature (e.g., ``a group of class 2''), and those that are part of
the text (e.g., a label or a year).  Mathematical expressions are, as
usual, enclosed within dollar signs {\tt \$...\$}; roman text elements
should be coded as \ttcs{rom\{...\}} in non-roman environments such
as theorems.

The version 2.0 preprint style did not include a definition of \ttcs{rom};
it was added in version 2.1.  if you are using version~2.0, insert this
definition into the preamble of your file to make \ttcs{rom} available.
\beginexample{}
\\define\\rom\#1\{\{\\rm \#1\}\}
\endexample

Abbreviated forms of mathematical terms are also usually set in roman
type, to distinguish them from mathematical variables or constants.
Use the control sequences for common mathematical functions and
operators like $\log$ and $\lim$ (see \cite{Joy\rm, Chapter 14}).

The style of reference citations is publication dependent.  In order
to ensure consistency, always use \ttcs{cite} when citing a reference.
Although the reference indentifier is roman in the preprint style, it
may be set automatically in bold in some publications, so you will
need to set any additional information in roman type as illustrated by
the coding of the citation in the previous paragraph:
\beginexample{}
\\cite\{Joy\\rm, Chapter 14\}
\endexample


\subhead Figures, tables, and other inserts with captions\endsubhead
%%
Figures, tables, and some other kinds of objects are usually handled as
inserts.  These objects may be prepared separately from the main document
and pasted in, in which case space must be left for them.  Sometimes,
however, a table or certain kind of figure (e.g.\ a commutative diagram)
can be prepared with \TeX, but it may be so large that fitting it in at the
point of reference may cause problems with paging.  In either case, the
object should be specified as a floating insert, which can be repositioned
automatically as required for good pagination.  AMS guidelines provide that
such an object should follow as closely as possible its first reference
in text, if possible on the same page where it is mentioned.  When this
is not possible, a reference will be added, ``(See Figure $n$, page $m$.).''

An author should use the control sequence \ttcs{topinsert}, which
specifies that an insert is to go at the top of a page.  If an insert
does not fit on the page where specified, \TeX{} will automatically
shift it to the top of the next page.
The final placement of inserts will be determined by the AMS editorial
staff, on the basis of the most appropriate page layout.

These floating objects usually have captions; a caption is usually
positioned above a table and below a figure.

This is the general structure used to specify a figure insert, with a
caption at the bottom.
\beginexample{}
\\topinsert
\ttcs{vspace}\{\Dimen\}\quad{\rm or}\quad%
  \<optional code for the insertion body>
\ttcs{captionwidth}\{\Dimen\}\quad{\rm(optional)}
\\botcaption\{\<caption label>\}
\ \<optional caption text>
\\endcaption
\\endinsert
\endexample

The general structure for a table insert, with a caption at the top,
is the following.
\beginexample{}
\\topinsert
\ttcs{captionwidth}\{\Dimen\}\quad{\rm(optional)}
\\topcaption\{\<caption label>\}
\ \<optional caption text>
\\endcaption
\ttcs{vspace}\{\Dimen\}\quad{\rm or}\quad%
  \<optional code for the insertion body>
\\endinsert
\endexample

The \ttcs{vspace\{\Dimen\}} option should be used to leave blank space
for an object to be pasted into place.
If a \Dimen{} is specified, its value should be the exact height of the
object to be pasted in.  Extra space around the object and the caption
are dependent on the document style and will be provided automatically.

The \ttcs{captionwidth\{\Dimen\}} option may be used to override the default
caption width specified by the document style.  For the preprint style,
the default caption width is 4pc narrower than the page width (30pc).
In the preprint style, a figure (bottom) caption narrower than the
caption width will be centered on the text width of the page.

The \<caption label> is something like ``Figure~1'' or ``Table~2a''.
Do not type any final punctuation; it will be provided.  The caption
label will be set in caps and small caps.

The \<optional caption text> is any descriptive text that may be desired. 
The preprint style will set this in roman.  Even if there is no text, the
\ttcs{endcaption} tag must be present.

If you choose to include the \TeX{} code for a figure, table, or other
captioned object in the input, then omit the \ttcs{vspace\{\Dimen\}} line
and type the code in the area indicated.  The size will be calculated
automatically and the caption set in the appropriate location above or
below the object.

Separate art work should be drawn in black ink with clean, unbroken
lines on nonabsorbent paper.  Labels should match those used in the text.
Authors' originals are used whenever possible in AMS journals; for
articles in a book series, art may be redrawn for consistency of style
throughout a volume.

The originals of photographs or computer-generated images should be sent
to the AMS as part of the art package.  For a color image (whether it
will be converted to a black and white image or appear in color), the
color negative or transparency is needed.  To avoid damage to photographic
images, do not use paper clips or staples, and do not tape them to a
sheet of paper.  A photocopy of such an image can be used to identify it.

There are no special macros to support the creation of tables in \AmSTeX{}.
Table macro packages, which are available from other sources, can be
used, but tables prepared in this way should be placed in a separate file
and processed separately.  {\tt.dvi} files for separately processed tables
can be sent to the AMS on diskette for output on the typesetter; this
is encouraged, as it will ensure output of high quality equivalent to
that of the article or monograph.  ({\tt.dvi} files, like other binary
files, cannot be sent via ordinary electronic mail.)

\head 5. Bibliographic references
\endhead
%%
The references section of a paper begins with \ttcs{Refs} and ends with
\ttcs{endRefs}.  \ttcs{Refs} sets the head for the references, switches
to eight-point type and makes a few other changes behind the scenes,
and \ttcs{endRefs} restores the body style.  This is convenient in
documents where small bibliography listings are scattered throughout,
as in some survey papers.

In a monograph, where the bibliograpy forms a separate chapter, the
chapter title should be entered in the manner described in the
\secref{Monograph formatting} section below.  After the top matter,
the line \ttcs{Refs\\nofrills\{\}} should be entered to set up the
proper references format.

Items in the bibliography are usually ordered alphabetically by author.
They may be numbered consecutively or labeled with some other ``key.''
These references are set with hanging indentation.  The amount of
indentation is preset to accommodate the most common case of reference
labels, two-digit numbers.  It can be increased (or decreased) by
specifying the widest number or key used in the references. For example,
\beginexample{}
\\widestnumber\\no\{999\}
\\widestnumber\\key\{GHMaR\}
\endexample
\noindent
will increase the indentation to accommodate a three-digit number or the
key \hbox{[GHMaR]} respectively.  (Only one style of reference labels
should be used in a manuscript, of course.)  Note that the parts of the
formatting that depend on the current publication style are taken into
account automatically (the period after a number or the [\dots]\ around a
key, plus the usual space). You can also specify
\ttcs{widestnumber\\no\{9\}} to reduce the indentation from two digits'
worth to one, if your bibliography has fewer than ten entries.

The elements of a bibliographic reference should be given in the order
and with the tags listed below.  Those that are required are so marked.
Examples are given in the two sample papers that accompany these \GL\/;
relevant references are cited with most tags by labels in [brackets].


\subhead All references\endsubhead
%%
Several tags must be present for all reference items.  The beginning and
end of each item must be indicated explicitly.  Otherwise, only the
beginning of a new element is marked by the presence of a tag.  Final
punctuation should always be omitted, except where noted explicitly.

\ttcs{ref} \req{} is used to indicate the beginning of a reference; the
  end of each reference must be indicated by \ttcs{endref}.

\ttcs{no} or \ttcs{key} \req{} is used to specify the reference number or
  label by which citations to the reference are referred in the text of the
  paper.  (Numbered references are used in the sample article, and references
  with keys in the sample monograph chapter that accompany these \GL.)

\ttcs{nofrills} may precede a tag to suppress the final punctuation on the
  preceding element (see \cite{15} in sample article); it may also follow
  a tag to suppress the punctuation at the end of the data identified by
  that tag (see \cite{23} in sample article).


\subhead Journal articles\endsubhead
%%
{}\endgraf  % no text with this heading, intentionally

\ttcs{by} \req{} indicates the beginning of the author name(s) (see \cite{4},
  \cite{8}, et al.\ in sample article).  Give at least one full name;
  initials and last name is an acceptable form.  If a subsequent reference
  is by the same author(s), use \ttcs{bysame} instead, with no data
  following it (see \cite{8}).

\ttcs{paper} \req{} marks the beginning of the title (see \cite{4},
  \cite{5}, et al.\ in sample article).
  In a title the first word and any proper names should begin with capital
  letters; everything else should be lowercase.  (In a German title, all
  nouns should begin with capital letters (see \cite{11}).)
  If a title is followed by a part number, the title proper should be
  terminated by a period, and the part number coded as \ttcs{rom\{...\}}
  (see \cite{11}, \cite{15}).

\ttcs{paperinfo} is used to tag additional information about the title
  of an article, such as an addendum (see \cite{17} in sample article)
  or part number (see \cite{22}).

\ttcs{jour} \req{} begins the name of the journal, in abbreviated form
  (see \cite{4}, \cite{8}, et al.\ in sample article).  Refer to
  {\it Abbreviations of Names of Serials Reviewed in Mathematical Reviews\/}
  \cite{ASMR}, to annual indexes of {\it Mathematical Reviews\/}, or to
  the American Standard for Periodical Title Abbreviations (National
  Clearing House for Periodical Title Word Abbreviations, Columbus, Ohio,
  1969) for standard journal abbreviations.  If the journal name is
  modified by a series name, include that information following the name,
  in parentheses (see \cite{24}).

\ttcs{vol} is used to tag the volume number (see \cite{5}, \cite{17},
  et al.\ in sample article).

\ttcs{issue} is used to tag the issue number (see \cite{17} in sample
  article); this should be omitted except where to do so would result
  in an ambiguous reference.

\ttcs{yr} \req{} tags the year of publication.  If the paper has not yet
  appeared in print, \ttcs{toappear} should replace the year (see \cite{7}
  in sample article).  For some journals, the volume number is the same
  as the year of publication (see \cite{17}); in such a case, \ttcs{vol}
  should be used, not \ttcs{yr}.

\ttcs{pages} should be followed by the span of pages covered (see \cite{4},
  et al.\ in sample article).  Use \ttcs{page} if the reference is only
  one page in length (see \cite{17}).

\ttcs{lang} is used to tag language information (see \cite{17}, \cite{24}
  in sample article).  This is used most often to identify Russian articles
  when their titles have been translated.

\ttcs{finalinfo} may be used to include additional relevant information,
  e.g.\ ``(overview)'' (see \cite{15} in sample article); note the use of
  \ttcs{nofrills} in this example.


\subhead Books\endsubhead
%%
This form of reference should be used only for complete books.  This will
ordinarily be either a monograph or a reference to an entire collection,
but it may also be used for dissertations, reports, and similar documents.

\ttcs{by} or \ttcs{bysame} \req{} are used in the same way as for a journal
  article (see \cite{1}, \cite{2} in sample article).
  If the reference is to an edited collection, such as the proceedings of a
  conference, insert ``(ed.)''\ or ``(eds.)''\ following the name(s) as
  appropriate (see \cite{9}, \cite{13}).

\ttcs{book} \req{} tags the title of the book (see \cite{1}, \cite{8} in
  sample article).  Dissertations are best treated as books (see \cite{7}).
  Collections referred to as a whole should also be entered as books (see
  \cite{9}, \cite{13}).  Part numbers should be treated the same as for
  papers, using \ttcs{rom\{...\}} (see \cite{1}, \cite{2}).

\ttcs{bookinfo} is used to tag book information in addition to the title,
  such as edition (see \cite{3} in sample article), identification of the
  reference as a dissertation (see \cite{7}), identification of a
  conference and its location in the case of a proceedings volume
  (see \cite{9}), etc.

\ttcs{publ} \req{} tags the name of the publisher; use abbreviated form
  (see \cite{1}, \cite{6}, et al.\ in sample article).

\ttcs{publaddr} \req{} is followed by the name of the city and state or the
  foreign city where the book was published (see \cite{3}, \cite{10},
  et al.\  in sample article).

\ttcs{yr} \req{} is the same as for a journal article (see \cite{1},
  \cite{3}, et al.\ in sample article).

\ttcs{lang} is the same as for a journal article (see \cite{1} in sample
  article).

\ttcs{finalinfo} is the same as for a journal article.


\subhead Articles in books\endsubhead
%%
These references contain elements common to both journal articles and
book references.

\ttcs{by} or \ttcs{bysame} \req{} are used in the same way as for a journal
  article (see \cite{10}, \cite{19} in sample article).

\ttcs{paper} \req{} likewise is similar to a journal article (see \cite{10},
  \cite{18} in sample article).

\ttcs{inbook} \req{} is followed by the title of the book (see \cite{10},
  \cite{16} in sample article).
  In this title, all important words begin with capital letters.  If the
  book is the proceedings of a conference, the location and date of the
  conference should follow the title in parentheses (see \cite{16}).

\ttcs{ed} or \ttcs{eds} \req{} is followed by the name of the editor or
  editors, respectively (see \cite{21} in sample article).

\ttcs{bookinfo} is similar to a book reference (see \cite{6} in sample
 article).  (Note also the use of \ttcs{nofrills} in this reference.)

\ttcs{vol} is used to tag volume information for a book series.  Only the
  volume number should be input; ``vol.''\ will be provided (see \cite{10}
  in sample article).

\ttcs{publ} and \ttcs{publaddr} \req{} are used in the same way as for books
  (see \cite{10}, \cite{16}, \cite{19} in sample article).

\ttcs{yr} \req{} is the same as for a journal article (see \cite{10},
  et al.\ in sample article), as is \ttcs{toappear} (see \cite{19}).

\ttcs{page} or \ttcs{pages} is the same as for a journal article (see
  \cite{10}, et al.\ in sample article).

\ttcs{lang} is the same as for a journal article.

\ttcs{finalinfo} is the same as for a journal article.


\subhead Extended references\endsubhead
%%
Sometimes several references are listed together, for example, parts of a
long paper that have been published separately.  Another type of reference
that can list multiple sources is a work cited both in the original and
in translation.  In either case, after the first reference is complete,
one of the tags below indicates the beginning of an additional reference;
this subsequent reference should be coded with all the tags appropriate
to the type of reference in the same order as for a first reference.

\ttcs{moreref} is used to indicate the beginning of an additional full
  reference; it takes no data, but is followed by the tags and data
  appropriate to the type of reference (see \cite{15}, \cite{17} in
  sample article).

\ttcs{transl} is followed by the information that describes a translation
  (see \cite{1}, \cite{2}, \cite{23} in sample article).
  The tags and data for the translated work follow in the same order
  as for an ordinary reference.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\head 6. Monograph formatting
\endhead
%%
A monograph will usually consist of multiple chapters.  Several features
are available in the preprint style that will set your output as a
chapter rather than as an individual paper.  For example, the positioning
of the title on the first page is different; also the text of a \ttcs{head}
in a monograph will be boldface instead of caps and small caps; headings
of theorems, propositions, definitions, remarks, etc., will be caps and
small caps instead of boldface, and indented rather than flush left.

For most AMS book series, authors can obtain style files with instructions
for the particular book from the Publications Department.  (Write to the
address given in the \secref{How to submit a file} section.)

Using the preprint style, each chapter must be prepared as a separate
document in a separate file.  These files should be given meaningful
names, so that when they are transmitted to the AMS, there will be no
question about which file represents which chapter.

Information that identifies the author(s), the subject matter of the
monograph, acknowledgments of support, and so forth, will appear in the
front matter of the book.  Place this information in a file called
\filnam{bookinfo.fil} and use the tags associated with the top matter of
an article.  (See the \secref{Top matter} section.)

In each chapter file, you must signal your intentions by typing
\ttcs{Monograph} in the preamble, right after the \ttcs{documentstyle}
line.

A typical monograph chapter would begin like this:
\beginexample{}
\\input amstex
\\documentstyle\{amsppt\}
\\Monograph
\\topmatter
\\title\\chapter\{4\} Matrix Algebras\\endtitle
\\endtopmatter
\endexample


\subhead Chapter titles\endsubhead
%%
There are three common variations of the chapter title, of which the form
shown above with a chapter number is most common.  Here the number that
follows \ttcs{chapter} is converted automatically to roman numerals and
the word ``{\eightpoint CHAPTER}'' is added.  (The second sample paper
that accompanies these \GL\/ illustrates the format of such a monograph
chapter.)

The second variation is a chapter title in which some other heading,
such as ``Appendix,'' replaces the word ``Chapter.''  In such cases
\ttcs{nofrills} is used:
\beginexample{}
\\topmatter
\\title\\chapter\\nofrills\{APPENDIX B\} Poisson Integral\\endtitle
\\endtopmatter
\endexample
\noindent The replacement text given with \ttcs{chapter} will appear
exactly as typed.

The third variation is used for an element such as a preface or
introduction, which has no pretitle text at all.  For this, omit the
\ttcs{chapter} command:
\beginexample{}
\\topmatter
\\title Preface\\endtitle
\\endtopmatter
\endexample


\subhead Table of contents\endsubhead
%%
In monographs, the table of contents should be a separate chapter.
Start by typing the title ``Contents'' as for a preface or introduction,
and then use the \ttcs{toc...\\endtoc} structure as the body of the
document (rather than putting it in the top matter, as you would for a
journal article).
\beginexample{}
\\topmatter
\\title Contents\\endtitle
\\endtopmatter
\bigskip
\\document
\\toc
\\title Preface\\page\{vii\}\\endtitle
\\title\\chapter\{1\} Matrix Algebras\\page\{1\}\\endtitle
\\head\{\} Continuous complex-valued functions\\page\{1\}\\endhead
\\subhead\{\} Examples\\page\{4\}\\endsubhead
...
\\title Appendix B. Poisson Integral \\page\{297\}\\endtitle
\\title Bibliography\\page\{307\}\\endtitle
\\endtoc
\\enddocument
\endexample


For the table of contents chapter titles are typed in a form similar, but
not identical, to that used for the title at the beginning of a chapter.
In particular, the second variation (the one for which \ttcs{nofrills} was
used) is typed without a \ttcs{chapter} tag; instead, put a period after
the text that appeared as an argument to \ttcs{chapter}.  The other two
variations are typed the same way for both chapter titles and tables of
contents.

To put page numbers in the table of contents, use \ttcs{page} as shown,
just before the ending of an element.  This option is available for
all levels of headings.

If a \ttcs{head}, \ttcs{subhead}, or \ttcs{subsubhead} entry does not
have a section number, it is necessary to follow that tag with an empty
group ({\tt \{\}}) followed by a space.  The contents macros look for
the space in order to align the section titles properly.


\subhead Monograph running heads\endsubhead
%%
In a monograph prepared using the preprint style, the chapter title is
used for the left running head and the text of section headings
(from \ttcs{head}) appears as the right running head.  
It is not uncommon for the text of a heading to be too long to fit
in the running head width; in such a case use \ttcs{rightheadtext} to
specify a shortened form of the heading for use in the running heads:
\beginexample{}
\\head Fourier coefficients of continuous periodic functions
of bounded entropy norm\\endhead
\\rightheadtext\{Fourier coefficients of periodic functions\}
\endexample
\noindent This should follow immediately after the \ttcs{head}, to ensure
that both take effect on the same page.  If the chapter title is too long
to fit as a running head, a shortened form can be supplied in a similar
way with \ttcs{leftheadtext} immediately after the \ttcs{title}.
See also the \secref{Running Heads} section.

\head 7. How to submit a file
\endhead
%%
First send two proof copies of the manuscript to the appropriate journal
or book series editor.  You should state your intention to submit the
manuscript electronically, but the electronic version should not
accompany the proof copy.  Upon acceptance of the paper, the source file
should be sent to the Providence office.

Before sending the source file, be sure to proofread your article or
monograph carefully, as if you were preparing it for publication
yourself---you are!  The files that you send must be the ones used to
prepare the proof copy that was accepted for publication.

The source file may be submitted either by electronic mail or on
diskette.  Whichever method is used, a few simple guidelines apply.
\roster
\item An \AmSTeX{} manuscript should be prepared using the ``preprint
   style'' according to the guidelines given above, plus whatever
   additional guidelines may have been given in instructions for
   a particular journal or book series.
\item Two printed copies of the manuscript, including art, should be
   sent to
\beginexample{\advance\exindent by\rosteritemwd \rm}
   Publications Department
   \AMS
   201 Charles St.
   P. O. Box 6248
   Providence, RI 02940-6248
\endexample
   \noindent
   The printed manuscript should indicate that the article was
   prepared and submitted electronically.  (The notice ``Typeset
   by \AmSTeX{}'' inserted by the preprint style is sufficient.)
\item The files should be complete, including your personal macro set
   if one was used.  (If the manuscript is a single paper, personal
   macros should be installed in the preamble, so that only one file
   is needed.)  The files should be the same versions used to prepare
   the printed copy.
\item Only necessary files should be sent.  Do not include {\tt.dvi} or
   transcript files; one of the first steps in processing is to
   \TeX{} the files you have sent using the AMS production headers.
\item Use meaningful file names, and include the file name in a comment
   at the top of the file.  (See the sample paper input for an example.)
\item A covering letter (electronic, if the files are sent by electronic
   mail) should identify the author(s) and title of the paper, the
   publication in which it is to appear, and include a list of the files
   being sent, stating the significance of each.  If there is only one
   file and it is being sent by electronic mail, the file should be
   appended to the letter and both sent in a single message.
\endroster

\noindent
Only files for articles that have been accepted for publication will
be processed.  Files for which no approval has been transmitted by the
journal or book series editor will be held until approval is received.


\subhead Submitting files by electronic mail\endsubhead
%%
Files sent by electronic mail should be addressed to the Internet address
\beginexample{\rm}
pub-submit\@Math.AMS.com
\endexample

If the manuscript comprises more than one file, each file (or part of a
file) should be sent in a separate message.  The subject line of the
message should identify the file by name; if one file has been broken
into parts on account of its large size, also identify the part---``part
$n$ of $m$''---in the subject line.

Files received by electronic mail will be acknowledged within five
business days.  If you do not receive an acknowledgment within that
time, please inquire; see the \secref{Getting help} section below.


\subhead Submitting files on diskette\endsubhead
%%
Files may be sent on diskettes in any standard format and density
appropriate for either IBM PC-compatible or Macintosh.
Label diskettes with your name, the title of your paper, and the
publication for which it is intended.  Diskettes and covering letters
should be sent to the Publications Department at the address shown above.

As diskettes are reusable, please make sure that all irrelevant files
that may remain from other work have been deleted.  Time spent by the
production staff in trying to identify extra files will delay processing
of your paper.

A package containing a diskette should be clearly marked ``Floppy disk.
Do not fold or bend.  Do not expose to electric motors or other
magnetic fields.''  Mailers designed for diskette shipment are available
from many sources; if you do not use a special mailer, cardboard or some
other stiffener should be enclosed in the package for protection.

Files received on diskette will be acknowledged as soon as possible
after they are received.  If you have not received an acknowledgment
within a reasonable amount of time (two weeks if you are located in
the North America, three weeks if in Europe, Australia, Japan, or
South America, a month if you are in Eastern Europe or Asia), please
inquire, writing to the same address to which you sent the diskette.

\head 8. What happens to a file once it reaches the AMS
\endhead
%%
When an electronic manuscript is received, the files are logged in for
tracking through the production process and matched with the paper
copy of the manuscript if that was sent separately.  Once it has been
determined that everything has been received, the files are sent to
the Composition Department for preliminary processing.  At this stage,
only those steps are taken that are necessary to ensure that the files
will run successfully with the production headers.  These steps include
the following.
\roster
\item Make additions or changes necessary to conform to the requirements
   of the production headers; this may include adding journal volume
   and issue numbers, for example.
\item Scan the preamble and remove any definitions that conflict with
   definitions in the production headers.
\item Remove hard-coded spacing that is intended only for formatting;
   this includes \ttcs{vskip}, \ttcs{bigskip}, control spaces, and
   the like.  Some spacing commands will be retained, in particular
   those that leave space for insertion of figures or tables or
   those included for the sense of mathematical expressions, for
   example the thinspace in $dx\,dy$ ({\tt\$dx\\,dy\$}).
\item Run the files through \AmSTeX{} using the production headers.
   Make adjustments as necessary until this \AmSTeX{} run is error-free.
\endroster

The AMS production headers will be different in several respects from the
headers used by the author.
\roster
\item Times Roman fonts will be used, rather than the Computer Modern
   used for the preprint and other styles distributed to authors.
\item Page dimensions may be changed, depending on the publication.
   The style and formatting of the top matter may also differ.
\item The publication logo and copyright notice will be present, and the
   notice ``Typeset by \AmSTeX{}'' will be removed.
\endroster
The output of this \AmSTeX{} run is delivered to the Editorial Department, %
where it is assigned to a production editor.
This proof is marked to note changes that must be made so that it will
conform to the style of the journal or book series.

The proof is returned to the Composition Department, where the marked
corrections are made in the files.  It is usually this stage that is most
sensitive to inconsistencies in the input coding.  For example, assume
that a control sequence has been defined to replace a frequently used
expression, but some instances of that expression in the text are spelled
out rather than input with the control sequence.  If the expression needs
to be changed corrections are marked on occurrences of the expression in
the proof text. When making corrections the keyboarder will find the
corresponding control sequence in the file text and will change the
definition, but will then assume that the definition has been used
throughout and will not look for exceptions.  It is for this reason you
must use the control sequence for every occurrence of the expression.

After corrections, the file is rerun through \AmSTeX{}, and the output
returned to the Editorial Department.  The corrections are checked, and
anything that does not conform to the previous markings is marked again.
This marked proof is then returned to the author for approval.

Any minor changes or corrections the author wishes to make after
receiving the marked proof should be submitted on paper.  Extensive
revision is not allowed at this stage.  Changes will be copymarked and
keyed by the Providence staff as for a non-electronic manuscript.
Electronic corrections or completely new submissions are not accepted.

\head 9. Checklist
\endhead
%%
Please use the following list in your final check as you package
your files to be sent to the AMS.

\roster
\item Top matter is complete.  Title, author(s), address(es), including
   current and e-mail addresses, subject classification(s), and (for a
   journal paper except in the \JAMS\/) abstract are required.  If
   appropriate, the \ttcs{thanks} footnote states whether the manuscript
   is preliminary or in final form.
   For a monograph, the overall ``top matter'' is included in a separate
   file \filnam{bookinfo.fil}.
 
\item Author-defined macros have been used throughout, for every occurrence
   of the strings or expressions that they define.
\item All author-defined macros are isolated in the preamble; for a
   multi-chapter monograph, the same macros should be included in the
   preamble of every file.
\item No \TeX{} commands have been used that are intended for formatting;
   you have used only the tags provided in the preprint style.
\item You have proofread the manuscript carefully and thoroughly.
\item All files referred to in the job are included, and they have
   meaningful names.
%%   No nested roster support in AMS-TeX; use PLAIN techniques.
 {%
  \itemitem{(a)} If files are being sent on diskette, no unnecessary
    files are present.
  \itemitem{(b)} If files are being sent by electronic mail, only one
    file is sent for an article, and an explanatory message has been
    included at the top of the file.  For a monograph comprising multiple
    files, each file is sent in a separate message with a subject line
    that identifies it clearly.  If any large file must be broken into
    pieces, the subject line also identifies which part of how many.
  \par}
\item The files that are being sent are the same ones that produced the 
    proof output.
\item A covering letter or explanatory message identifies the author(s),
   title, intended publication (journal or series), and list of files.
\item The covering letter or explanatory message also tells how you can be
   reached throughout the publication process.  Be sure to notify us if your
   address changes during this period.

Four appendixes accompany these \GL.  These comprise two samples, each
in two forms: output and input.
\roster
\item"(A)" The first sample represents a paper suitable for publication
  in a journal or in a collection such as a volume of conference
  proceedings.
\item"(B)" The input corresponding to the sample paper; the input file
  is named \filnam{amst-art.tex}.
\item"(C)" The second sample represents a monograph, with a table of
  contents, one chapter, and a bibliography.
\item"(D)" The monograph input consists of three parts:
{%
  \itemitem{(1)} Table of contents; the input file is named
    \filnam{amst-mtc.tex}.
  \itemitem{(2)} Chapter; the input file is named
    \filnam{amst-mon.tex}.
