%\section{Introduction}
%\label{sec:intro}
%
% The \emph{Annals of Mathematics} is published bimonthly with the
% cooperation of Princeton University and the Institute for Advanced
% Study. Founded in 1884 by Ormond Stone of the University of
% Virginia, the journal was transferred in 1899 to Harvard University,
% and in 1911 to Princeton University. Since 1933, the Annals has been
% edited jointly by Princeton University and the Institute for
% Advanced Study (see
% \url{http://annals.princeton.edu/annals/about/journal/about.html}). 
% 
% This class presents a complete redesign of the journal style---with
% new fonts and new interface.  
%
%
% An author well acquainted with AMS\LaTeX{} should find this package
% easy to use and configurable.  The User Manual below illustrates the
% basic use of the class and discusses the differences with \progname{amsart}.
% For an in-depth tutorial of AMS\LaTeX{} I could recommend the
% excellent book~\cite{Graetzer00:MathIntoLaTeX}.
%
%
%\section{User's Guide}
%\label{sec:manual}
%
%
%\subsection{Installation}
%\label{sec:installation}
%
% The installation of the class follows the usual
% practice~\cite{TeXFAQ} for \LaTeX{} packages:
% \begin{enumerate}
% \item Run \progname{latex} on |aomart.ins|.  This will produce the file
% |aomart.cls|.
% \item Put the file |aomart.cls| to
% the place where \LaTeX{} can find them (see
% \cite{TeXFAQ} or the documentation for your \TeX{}
% system).\label{item:install} 
% \item Update the database of file names.  Again, see \cite{TeXFAQ}
% or the documentation for your \TeX{} system for the system-specific
% details.\label{item:update}
% \item The file |aomart.pdf| provides the documentation for the
% package (this is the file you are probably reading now).
% \end{enumerate}
% As an alternative to items~\ref{item:install} and~\ref{item:update}
% you can just put the files in the working directory where your
% |.tex| file is.
% 
%
% The class uses some other \LaTeX{} classes or packages.  Most
% probably, they are already installed on your system.  If not (or if
% their versions are very old), you need to download and
% install them.  Here is the list:
% \begin{enumerate}
% \item \progname{amsart} class and related
% packages~\cite{Downes04:amsart}, 
% \item Package \progname{hyperref}~\cite{Rahtz06:Hyperref},
% \item \progname{ifpdf} package~\cite{Oberdiek06:Ifpdf},
% \item \progname{fancyhdr} package~\cite{Oostrum04:Fancyhdr},
% \item \progname{cmtiup} package~\cite{Znamenskii03:Cmtiup} for
% ``special italics'' with uprgiht digits and punctuation.  Note that
% since many distributions do not include this package, you may need
% to install it yourself.  Just download the file
% \url{http://mirrors.ctan.org/fonts/cm/cmtiup.zip}, unzip it in your
% \path{TEXMF} directory and rebuild the file names database  with the
% command like |mktexlsr|,
% \item \progname{yhmath} package~\cite{Haralambous96:Yhmath}.
% \end{enumerate}
% 
%
%\subsection{Invocation}
%\label{sec:invocation}
%
% To use the class, put in the preamble of your document
% \begin{flushleft}
% |\documentclass[|\meta{options}|]{aomart}|
% \end{flushleft}
% The class internally loads \progname{amsart}, so all facilities of
% \progname{amsart}~\cite{Graetzer00:MathIntoLaTeX, amsldoc} can be used in the
% source.
%
%  The class should work with the
%  \progname{Babel}~\cite{Braams05:Babel} package.  At present,
%  English, French and German languages are fully supported.  See also
%  Section~\ref{sec:non-english}.  
% 
% \DescribeOptions{draft,final}
% The options |draft| and |final| work in the same way as for
% \progname{amsart} and standard \LaTeX.  If the option |draft| is
% chosen, the overfull lines are marked by black boxes on the margins
% \emph{and} the |\includegraphics| prints blank placeholders for the
% images.  The option |final| (default) switches off the marking of
% overfull lines and restores the behavior of |\includegraphics|.  To
% switch on just the overfull marks, without changing the behavior of
% |\includegraphics|, one can either explicitly pass the option final
% to \progname{graphics} package:
% \begin{verbatim}
% \documentclass[draft]{aomart}
% \usepackage[final]{graphics}
% \end{verbatim}
% or add in the beginning of the document
% \begin{verbatim}
% \overfullrule=5pt
% \end{verbatim}
% 
% \DescribeOption{manuscript}
% The option |manuscript| is intended to faciliate the communications
% between the editor and the author.  It enables two things:
% \begin{enumerate}
% \item Numbering of lines in the manuscript is switched off in the
% normal mode, but is on in the manuscript mode.
% \item Command |\EditorialComment| is no-op in normal mode, but
% produces mariginal commentaries in the manuscript
% \item Hyperlinks are black in normal mode, but blue in manuscript
% mode. 
% \end{enumerate}
% 
% \DescribeOption{screen}
% The option |screen| is intended for the onscreen version of the
% acticle.  If this option is selected, the links are blue colored,
% and the margins are reduced.
%
% \DescribeOption{olddoi}%
% Starting from version~1.9 (2011) the formatting of DOI numbers
% changed according to the new recommendations from CrossRef.  The
% option |olddoi| switches on the ``old'' formatting.  It is used for
% compatibility reasons.
%
% \DescribeOption{doi2016}%
% Starting from version~1.5 (2016) the formatting of DOI numbers
% changed again according to Crossref recommendations.  The option
% |doi2016| switches to the version existed between 2011 and 2016.  
%
% \DescribeOption{oldkeywords}%
% Since June 2017 keywords and AMS Mathematical Subjects
% classification numbers are printed on the title page.  The option
% \texttt{oldkeywords} suppresses this.  
%
% \DescribeOptions{8pt,9pt,10pt,11pt,12pt}
% The size-changing options of \progname{amsart} class (|8pt|, |9pt|,
% \dots, |12pt|) have no effect other than producing a warning in the
% log since the journal is designed for 
% only one type size (roughly corresponding to |11pt| of
% \progname{amsart}).
%
%
% \DescribeOption{printscheme}%
% Normally the scheme for MSC numbers is not printed.  If the option
% |printscheme| is chosen, however, it is printed explicitly.
%
%
%\subsection{Top Matter}
%\label{sec:top_matter}
%
%
% There are two kinds of top matter commands:  the ones used primarily
% for authors and the ones used primarily for editors.  We describe
% them separately.
%
% The macros descibed below must be issued in the preamble of the
% document, i.e. before |\begin{document}|.  They produce fatal error
% otherwise.  This behavior is required by the way non-\TeX{} scripts
% process the files to produce  metadata.
%
% The only exception is abstract, which should be placed 
% after |\begin{document}|.
% 
%
%\subsubsection{Commands for Authors}
%\label{sec:authors_commands}
%
%
% \DescribeMacro{\title}
% The command |\title|, as in \progname{amsart} class, has two arguments:  one
% optional, and one mandatory:
% \begin{flushleft}
%   |\title[|\meta{ShortTitle}|]{|\meta{FullTitle}|}|
% \end{flushleft}
% The mandatory argument is the full title of the article.  The
% optional argument, if present, defines the shorter version of the
% title for running heads.  If the optional argument is absent, the
% full title is used instead.  
%
% The optional argument should be used in two cases: when the full
% title is too long to fit in the running head, \emph{and} when the
% author wants to add a footnote or linebreaks to the title.  
%
%
% \DescribeMacro{\author}%
% \DescribeMacro{\email}%
% \DescribeMacro{\address} \DescribeMacro{\curraddr}%
% \DescribeMacro{\urladdr}%
% \DescribeMacro{\orcid}%
% The interface for specifying the authors and their affiliations is
% close the the one of \progname{amsart}~\cite{instr-l} (and different
% from the standard \LaTeX).  For each author a separate command
% |\author| should be used, followed by |\address| and (optionally)
% |\curraddr|, |\email|, |\urladdr| and \cs{orcid}.  Note that the
% house style of the \emph{Annals of Mathematics} requires writing
% |\address| in the form \emph{Institution, City, State} (or
% \emph{Institution, City, Country} for non-US locations).  Like the
% newer versions of \progname{amsart}, \progname{aomart} does
% \emph{not} require the doubling of the |@| symbols in the e-mail
% addresses.  The macro |\author| has two arguments, similarly to
% |\title|:
% \begin{flushleft}
%   |\author[|\meta{AbbrevName}|]{|\meta{FullName}|}|
% \end{flushleft}
% The optional argument defines the shorter form of the author's name
% to be included in the running head.  
%
% \DescribeMacro{\givenname} \DescribeMacro{\surname} 
% The papers published in the \emph{Annals of Mathematics} are
% included in various databases.  For the indexing purposes it is
% important to correctly separate the authors' names into ``First
% Name/Surname'' parts.  This operation is not easy for the
% computers.  Therefore we decided that the authors should know best
% how to deal with their names.  The macros |\givenname| and
% |\surname| are used to indicate how to split the name into the
% parts. 
%
% \DescribeMacro{\fulladdress}
% Another command which does not affect the typesetting is
% \cmd{\fulladdress}.  It is used to store the full mailing address of
% the author for the online version of the journal and various
% databases.
%
% \DescribeMacro{\contrib}%
% Sometimes there are contributors to a paper, who are not full authors:
% the person may write an appendix or other part of the paper.  You
% can use the command \cs{contrib}\oarg{role}\marg{name} for
% indicating these persons.  Note that \oarg{role} argument has a
% special meaning, indicating that the role of this person is the same
% as for the previous contributor, for example,
% \begin{verbatim}
% \contrib[with Appendix~A by]{A. U. Thor}
% \givenname{Alexandra}\surname{Thor}
% \contrib{A. N. Other}
% \givenname{Antony N.}\surname{Other}
% \contrib[with Appendix~B by]{Y. Etanother}
% \givenname{Yakov}\surname{Etanother}
% \end{verbatim}
% In this example Appendix~A is written by A.~U.~Thor and
% A. N. Another, and Appendix~B is written by Y.~Etanother.
% Commands \cs{orcid}, \cs{email}, \cs{address}, \cs{fulladdress},
% \cs{givenname} and \cs{surname} can be used for contributors in the
% same way they are used for authors.  
%
% \DescribeMacro{\shortauthors}
% In some cases the authors list may be too long for the running head,
% even if the abbreviated forms are used for each author.  In this
% case it is possible to change the running head by a
% \emph{redefinition} of the command |\shortauthors|.  This
% redefinition must be done after all |\author| commands, but before
% |\maketitle|:
% \begin{verbatim}
% \renewcommand{\shortauthors}{A.~Smith et al}
% \end{verbatim}
%
%
% \DescribeMacro{\thanks}
% Like \progname{amsart} (and unlike standard \LaTeX{}),
% \progname{aomart} allows |\thanks| only \emph{outside} of commands
% |\title| and |\author|.
%
%
% \DescribeMacro{\copyrightnote}
% Normally each paper is copyrighted by Department of Mathematics,
% Princeton University.  This is reflected in the footnote on the
% first page of the article.  However, by arrangement with the
% editors, certain papers may have different copyright.  The command
% \cmd{\copyrightnote}\marg{copyright statement}, if issued, changes
% the footnote to the corresponding text, for example: 
% \begin{verbatim}
% \copyrightnote{\textcopyright~2012 by the authors.  This paper may
% be reproduced, in its entirety, for noncommercial purposes.}
% \end{verbatim}
% Note that if you issue this command, you should explicitly include
% both the copyright sign and the year unless the paper does not have
% a copyright, for example:
% \begin{verbatim}
% \copyrightnote{This paper is in the public domain}
% \end{verbatim}
% 
%
%
% \DescribeEnv{abstract}
% The abstract of the paper must be put between |\begin{abstract}| and
% |\end{abstract}|.   Unlike the situation in \progname{amsart}
% class, abstract may be put \emph{after} |\maketitle|.
%
% A paper may have several abstracts in different languages.  This
% sitation is discussed in Section~\ref{sec:non-english}.  
%
% \DescribeMacro{\maketitle}
% The macro |\maketitle| typesets the top matter.  All top matter
% information should be specified before this command.
%
%
%\subsubsection{Commands for Editors}
%\label{sec:editors_commands}
%
% The commands described in this section should be used by the editors
% to insert the information about the published paper.  They must be
% put before the |\maketitle| command.
%
% \DescribeMacro{\keyword}
% The command |\keyword| adds a keyword to the list of keywords.  This
% command may be repeated, for example
% \begin{verbatim}
% \keyword{Embedding theorem}
% \keyword{Relatively hyperbolic group}
% \end{verbatim}
% 
% \DescribeMacro{\subject}
% The command |\subject| has  three parameters: whether the subject is
% primary or secondary, the classification scheme and the subject
% itself, for example
% \begin{verbatim}
% \subject{primary}{msc2000}{20E45}
% \subject{secondary}{msc2000}{20F65}
% \end{verbatim}
%
% \DescribeMacro{\formatdate}%
% The macro |\formatdate| is used to format the dates in the
% commands.  Its argument is the date in the format |YYYY-MM-DD|, for
% example
% \begin{verbatim}
% \formatdate{2010-08-13}
% \end{verbatim}
% 
% \DescribeMacro{\received}
% \DescribeMacro{\revised}
% \DescribeMacro{\accepted}
% \DescribeMacro{\published}
% \DescribeMacro{\publishedonline}
% The commands |\received|, |\revised|, |\accepted|, |\published|,
% |\publishedonline| accept as a parameter a date in the form
% |\formatdate|\marg{YYYY-MM-DD}, for example
% \begin{verbatim}
% \received{\formatdate{2004-12-24}}
% \revised{\formatdate{2006-04-12}}
% \accepted{\formatdate{2007-10-02}}
% \end{verbatim}
%
% \DescribeMacro{\proposed}
% \DescribeMacro{\seconded}
% \DescribeMacro{\corresponding}
% \DescribeMacro{\editor}
% \DescribeMacro{\version}
% The macros |\proposed|, |\seconded|, |\corresponding|, |\editor|,
% |\version| are used to set the corresponding metadata for the
% editorial process, for example
% \begin{verbatim}
% \proposed{E. D. Itor}
% \seconded{A. S. Sociate}
% \corresponding{A. U. Thor}
% \version{2.1}
% \end{verbatim}
% 
% 
% 
% \DescribeMacro{\volumenumber}
% \DescribeMacro{\issuenumber}
% \DescribeMacro{\publicationyear}
% \DescribeMacro{\papernumber}
% \DescribeMacro{\startpage}
% \DescribeMacro{\endpage}
%  The macros |\volumenumber|, |\issuenumber|, |\publicationyear|,
%  |\papernumber|, |\startpage|, |\endpage| set up the corresponding
%  data for the paper, for example:
% \begin{verbatim}
% \volumenumber{172}
% \issuenumber{1}
% \publicationyear{2010}
% \papernumber{1}
% \startpage{1}
% \endpage{39}
% \end{verbatim}
% Note that if the argument of |\endpage| is empty, \LaTeX{} tries to
% calculate the last page number as best as it can.
%
% \DescribeMacro{\copyrightyear}
% In the standard copyright statement the copyright year is assumed to
% be the same as the |\publicationyear|.  However, for special cases
% one can set the copyright year explicitly, for example,
% \begin{verbatim}
% \publicationyear{2012}
% \copyrightyear{2011}
% \end{verbatim}
% Note that if you use your own copyright statement instead of the
% canned one (with the command \cmd{\copyrightnote}), you need to put
% there the copyright year explicitly instead of using this command.  
%
% \DescribeMacro{\doinumber}%
% \DescribeMacro{\mrnumber}%
% \DescribeMacro{\zblnumber}%
% \DescribeMacro{\arxivnumber}%
% The macros |\doinumber|, |\mrnumber| and |\zblnumber|  set the
% information about paper in four major reference databases:  DOI
% (\url{http://www.doi.org/}), MathSciNet
% (\url{http://www.ams.org/mathscinet/}, Zentralblatt MATH
% (\url{http://www.zentralblatt-math.org/zmath/}) and arXiv
% (\url{https://www.arxiv.org}).  The use of these  
% macros should be obvious: 
% \begin{verbatim}
% \doinumber{10.1215/S0012-7094-92-06520-3}
% \mrnumber{1154181}
% \zblnumber{0774.14039}
% \arxivnumber{1234.567890}
% \end{verbatim}
% Note the difference between these commands and the bibliography
% commands discussed in Section~\ref{sec:biblio}.  Commands in this
% Section set up the data for the \emph{current article.}  Commands in
% Section~\ref{sec:biblio} set up the data for the articles in the
% bibliography list.
%
% Normally you should \emph{not} use |\doinumber| command, since the
% class will construct the standard DOI for the paper from the volume,
% issue and paper information.  Use it \emph{only} if the result is by
% any reason wrong.
%
%
% \DescribeMacro{\oldsubsections}
% Starting with version~1.2 we decreased the vertical spacing before
% |\subsection|.  The command |\oldsubsections| restores the ``old''
% values.
%
%\subsection{Additional Macros}
%\label{sec:add_guide}
%
% \DescribeEnv{eqnarray}
% \DescribeEnv{eqnarray*}
% Thee class \progname{aomart} loads the class \progname{amsart}.
% Therefore all familiar \progname{amsmath} commands~\cite{amsldoc}
% are available.  In particular, there are many commands for writing
% multiline equations (|split|, |align|, |gather|, |multline|,
% \dots).  The environments |eqnarray| and |eqnarray*|, while still
% avilable, are \emph{not} recommended and should be avoided if
% possible.  
%
% \DescribeMacro{\widetilde}
% \DescribeMacro{\widehat}
% \DescribeMacro{\widetriangle}
% \DescribeMacro{\wideparen}
% \DescribeMacro{\widering}
% \DescribeMacro{\widebar}
%  A number of ``wide'' mathematical accents is available due to the
%  (internally loaded) package
%  \progname{yhmath}~\cite{Haralambous96:Yhmath}: |\widetilde|, 
% |\widehat|, |\widetriangle|, |\wideparen|, |\widering|, |\widebar|. See
% Table~\ref{tab:accents} for the example of the usage.  
%
% \begin{table}
%   \centering
%   \begin{tabular}{ll}
%     \toprule
%     Code & Example \\
%     \midrule
%     |\widetilde{AB}| & $\widetilde{AB}$\\
%     |\widehat{AB}| & $\widehat{AB}$\\
%     |\widetriangle{AB}| & $\widetriangle{AB}$\\
%     |\wideparen{AB}| & $\wideparen{AB}$\\
%     |\widering{AB}| & $\widering{AB}$\\
%     |\widebar{AB}| & $\widebar{AB}$\\
%     \bottomrule
%   \end{tabular}

% \DescribeMacro{\EditorialComment}
% The macro |\EditorialComment|\oarg{comments} typesets the comments

% needed}
% \end{verbatim}

% \DescribeMacro{\fullref}%
% \DescribeMacro{\pfullref}%
% \DescribeMacro{\bfullref}%
% \DescribeMacro{\eqfullref}%
% \DescribeMacro{\fullpageref}%
% A set of macros is used to make more convenient clickable references
% in the online versions of papers.  The
% package~\progname{hyperref}~\cite{Rahtz06:Hyperref} 
% makes clickable reference numbers in the phrases like
% \begin{verbatim}
% ...in theorem~\ref{thm:Noeter}...
% ...see equation~\eqref{eq:alpha}...
% \end{verbatim}
% However, it is more convenient for the readers if both
% the number \emph{and} the word ``theorem'' or ``equation'' were
% clickable.  The macros |\*fullref| solve this problem.  Each macro
% has two arguments:  the word and the reference, for example
% \begin{verbatim}
% ...in \fullref{theorem}{thm:Noeter}...
% \end{verbatim}
% The command |\pfullref| typesets
% the reference in parentheses.  The command |\bfullref| typesets it
% in brackets, and the command |\eqfullref| uses the |\eqref|
% command, for example,
% \begin{verbatim}
% ...see \eqfullref{equation}{eq:alpha}...
% \end{verbatim}
% The similar command  |\fullpageref| is used to make the word
% ``page'' clickable, for example,
% \begin{verbatim}
% ...see \eqfullref{equation}{eq:alpha} on
% \fullpageref{eq:alpha}...
% \end{verbatim}
% By default the command adds the word ``page'' to the text.  You can
% override this choice using the optiomal parameter, e.g.
% \begin{verbatim}
% \fullpageref[The page]{eq:alpha} starts the discussion of...
% \end{verbatim}
% 
%
%
% The \progname{Perl} script \path{fullref.pl} can be used to convert
% change all references to the |\fullref| commands.  It works in the
% following way:
% \begin{verbatim}
% perl fullref.pl original.pl > result.pl
% \end{verbatim}
% The script converts all instances of combinations
% ``|word \ref{reference}|'', ``|word~\ref{reference}|'' and
% ``|word~\pageref{reference}|'' to ``|\fullref{word}{reference}|, and
% similarly for parenthesized references, |\eqref| commands, and page
% references.  To prevent the converting, just put |\ref{reference}|
% or |\eqref{reference}| inside braces.  The ``word'' here must not
% start with a backslash (i.e. must not be a macro itself).  This
% prevents disastrous results for phrases like
% ``|see~\ref{a},  \ref{b}|''.
%
%
% The distribution includes two sample files, \path{aomsample.tex} and
% \path{aomsample1.tex}, the latter being obtained from the former by
% the script \path{fullref.pl}.
% 
%
% Note that |\autoref| command of \progname{hyperref} provides for
% another mechanism that achieves the same goal.  Unlike |\fullref|
% command, the command |\autoref| tries to figure out the name of the
% reference from the context.  See the manual~\cite{Rahtz06:Hyperref}
% for more information.
%
%\subsection{Theorems}
%\label{sec:theorems}
%
% \DescribeMacro{\newtheorem}
% You can use the commands of \progname{amsthm}
% package~\cite{amsthdoc} like
% |\newtheorem{lem}{Lemma}| for numbered theorems, or
% |\newtheorem*{KL}{Klein's Lemma}| for unnumbered theorems, or
% tune the numbering using the optional arguments of these commands.  
%
% To provide backward compatibility with some other classes used
% internally by the \emph{Annals of Mathematics,} the class provides
% yet another optional argument for the command |\newtheorem|,
% allowing constructions like |\newtheorem[\it]{lem}{Lemma}|.  This
% optional parameter is not used in our typesetting.
%
%
% The class provides two theorem styles:
% \begin{description}
% \item[plain:] This is the default theorem style.  It is used for 
% Theorem, Lemma, Proposition, Conjecture, Corollary and  Claim.
% \item[definition:] This style is used for Definition, Remark,
% Notation, Condition,  Example etc.
% \end{description}
% Note that AMS classes define the third theorem style,
% \textbf{remark.}  In our class remarks are typeset in the
% \textbf{definition} style.  To make the authors' lives easier we
% define the theorem style \textbf{remark,} which is identical to the
% theorem style \textbf{definition.}
%
%\subsection{Illustrations}
%\label{sec:illustrations}
%
% The authors can use the \progname{graphics}, \progname{graphicx},
% \progname{PSTricks}, \progname{pgf/tikz}, \progname{Metapost} or
% other tools to include illustrations
% (see~\cite{Goossens97:LateXGraphicsCompanion} for a comprehensive
% discussion of \LaTeX{} graphics possibilities).
%
%
%\subsection{Funding}
%\label{sec:ug_funding}
%
% \DescribeMacro{\funding}%
% There is a special command for showing the support for the paper, 
% \cs{funding}\oarg{text}\marg{sponsor}\marg{grantid}.  Normally it
% prints the name of the sponsor and in parentheses the id of the
% grant, if it is not empty.  However, you can override this using the
% optional argument of the command. For example, the following text
% \begin{verbatim}
% AB is grateful to \funding{NASA}{123GH456}, while MJ was supported
% by \funding{NIH}{}.  Both authors acknowledge \funding[the generous
% help of other agencies]{Department of Defense}{Special project
% grant}. 
% \end{verbatim}
% will expand to
% \begin{verbatim}
% % AB is grateful to NASA (123GH456), while MJ was supported
% by NIH.  Both authors acknowledge the generous
% help of other agencies. 
% \end{verbatim}
%
% The command will save the information about the grants in the form
% suitable for automatic processing.
% 
%
%\subsection{Bibliography}
%\label{sec:biblio}
%
% The authors are encouraged to use Bib\TeX{} for uniform style of
% bibliography.  The distribution includes the BST files
% \path{aomplain.bst} and \path{aomalpha.bst}.  These files have
% several additional non-standard fields:
% \begin{description}
% \item[mrnumber:] MathSciNet number for the article.
% \item[zblnumber:] Zentralblatt number for the article.
% \item[doi:] DOI number for the article.
% \item[jfmnumber:] JFM number for the article.
% \item[arxiv:] ArXiv reference for the ArXiv manuscript.
% \item[url:] If the reference is available online, the corresponding
% url. 
% \item[venue:] (for \texttt{conference} entries)  The place where the
% conference took place.
% \item[sortyear:] Some entries do not have a year set up (e.g. some
%   \texttt{unpublished} entries.  If you have several entries from
%   the same author, some with a year, and some without, you may want
%   to put them in a certain order.  The field |sortyear| overrides
%   |year| for the sorting purposes.
% \item[titlenote:] this field is like \texttt{note}, but is typeset
% immediately after a title.  It should be used for additional
% information, for example,
% \begin{verbatim}
% @Book{Knuth94:TheTeXbook,
%  author =	 {Knuth, Donald Ervin},
%  title = 	 {The \TeX book},
%  publisher = 	 {Addison-Wesley Publishing Company},
%  year = 	 1994,
%  series =	 {Computers \& Typesetting A},
%  address =	 {Reading, MA},
%  titlenote  =  {with illustrations by Duane Bibby}
% }
% \end{verbatim}
% \item[totalpages:] some articles (especially published in an electronic
% format) do not have start and end page numbers; instead you may put
% the total number of pages.   If both \texttt{pages} and
% \texttt{totalpages} are present, \texttt{pages} take precedence.

% \end{description}

%
% \DescribeMacro{\doi}
% \DescribeMacro{\mr}
% \DescribeMacro{\zbl}
% \DescribeMacro{\jfm}
% \DescribeMacro{\arxiv}
% There are several databases routinely used in the science and
% mathematics communities.  Among them are DOI, MathSciNet,
% Zentralblatt, Jahrbuch Database, ArXiv.  Many bibliographies include
% references to 
% these databases.  The commands |\doi|, |\mr|, |\zbl|, |\jfm|, |\arxiv| are
% used to typeset these  references.  If you use Bib\TeX{}, these
% commands are automatically used for the corresponding fields in your
% database entries.

%\subsection{Papers in languages other than English}
%\label{sec:non-english}
%
% The recommmended way to typeset papers in languages other than
% English is \textsl{babel} package~\cite{Braams05:Babel}.  For
% example, to typeset a paper in French (with an English abstract, see
% below), one puts in the preamble
% \begin{verbatim}
% \usepackage[utf8]{inputenx}
% \usepackage[english,frenchb]{babel}
% \end{verbatim}
%
% Such papers often contain several abstracts: for example, in the
% language the paper is written \emph{and} in English.  Accordingly,
% \textsl{aomart} allows several abstracts.  Each abstract must be put
% inside a group with the corresponding language selected using
% \cs{selectanguage} command, for example
% \begin{verbatim}
% {\selectlanguage{french}%
%   \begin{abstract}
%     French abstract
%   \end{abstract}}
%
% {\selectlanguage{english}%
%   \begin{abstract}
%     English abstract
%   \end{abstract}}

% 
% There are some papers published in languages other than English.

%
% First, let us define English defaults:

%
% \begin{macro}{\@aom@by}
% \changes{v1.10}{2011/06/21}{Added macro}
%   This is just ``By'' in English:

%    \end{macrocode}
% \end{macro}
%
% Now we can define internationalization:

%
% \begin{macro}{\EditorialComment}
% \changes{v0.3}{2010/09/28}{Added macro} 
%   This macro is noop in normal mode, but is a tiny marginpar in the
%   manusript mode
%    \begin{macrocode}
\def\EditorialComment#1{\if@aom@manuscript@mode\bgroup
  \marginparwidth=75pt\marginpar{\scriptsize\raggedright#1}\egroup\fi}

%
% \begin{macro}{\@fullref}
% \changes{v0.5}{2010/10/24}{Added macro} 
%   This macro creates a wide link for the reference.  It has four
%   parameters: the word (theorem, equation,\dots), the ``pre''
%   punctuation, the reference and the ``post'' punctuation.
%    \begin{macrocode}
\def\@fullref#1#2#3#4{\hyperref[#3]{#1~#2\ref*{#3}#4}}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\fullref}
% \changes{v0.5}{2010/10/24}{Added macro} 
%   A reference without parentheses:
%    \begin{macrocode}
\newcommand{\fullref}[2]{\@fullref{#1}{}{#2}{}}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\pfullref}
% \changes{v0.5}{2010/10/24}{Added macro} 
%   A reference with parentheses:
%    \begin{macrocode}
\newcommand{\pfullref}[2]{\@fullref{#1}{(}{#2}{)}}
%    \end{macrocode}   
% \end{macro}
% \begin{macro}{\bfullref}
% \changes{v0.5}{2010/10/24}{Added macro} 
%   A reference with brackets:
%    \begin{macrocode}
\newcommand{\bfullref}[2]{\@fullref{#1}{[}{#2}{]}}
%    \end{macrocode}   
% \end{macro}
% \begin{macro}{\eqfullref}
% \changes{v0.5}{2010/10/24}{Added macro} 
%   Here we do not use the standard common |\@fullref| because we want
%   |\eqref| to work\dots
%    \begin{macrocode}
\newcommand{\eqfullref}[2]{\hyperref[#2]{#1~\textup{\tagform@{\ref*{#2}}}}}
%    \end{macrocode}   
% \end{macro}
% \begin{macro}{\fullpageref}
% \changes{v1.25}{2021/04/10}{Added macro} 
%   A wide link for page reference.  Note that the word ``page'' can
%   be omitted
%    \begin{macrocode}
\newcommand{\fullpageref}[2][page]{\hyperref[#2]{#1~\pageref*{#2}}}
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\eqnarray}
% \changes{v0.9}{2010/12/04}{Redefined standard macro} 
%   While we do \emph{not} recommend the use of |eqnarray|, we still
%   would like to correct the ugly spacing around it\dots

% \begin{macro}{\funding}
% \changes{v1.27}{2022/04/30}{Added macro} 
% The macro to print grants.  It adds to the rpi file the information
