Using the HHA Class File

Introduction

The hha class file hha.cls is a LaTeX class file designed to produce articles for Homology, Homotopy and Applications. Be sure to always use the latest version available from our website. Also, please follow the style guidelines.

Using the class file

The file is used in a very similar way to the standard amsart article class, and automatically includes the amsmath features. It has some differences, mainly in an extended range of "front matter" commands to specify authors, addresses, received dates, and other such information.

A typical file may start something like the example shown below. You can also download this sample separately. All of the requested information must be filled in, except where noted.

% LaTeX-2e.  1 page.  Uses xypic.
\documentclass{hha}

% See http://intlpress.com/HHA/style/hhaguide.htm for more
% detailed instructions. 

% Example:
\usepackage{xy}

\begin{document}

% Title of document, usually lower case except for first word
% and proper nouns.  Avoid unnecessary symbols.
\title{Title of article} 

% If the title is too long for the running head, use
% the following command to specify a short title:
%\shorttitle{Shorter title}

\author{First Author}             % First Author
\email{fauthor@some.domain}       % First Author's email address.
% First author's postal address.  Do not use \\ to separate
% lines, just use ordinary line breaks like below.  It will
% appear on one line in the article, but will be used exactly
% as typed below to send a complimentary copy of the journal,
% so ensure that it is a complete postal address.
\address{Mathematics Department,
         Some University,
         Address,
         Country}
% If needed, use a \thanks command, but not inside the \author
% command.
% \thanks{The first author was supported in part by a grant.}

\author{Second Author}            % Second Author.
\email{sauthor@some.domain}       % Second Author's email address.
% Second author's postal address.  Do not use \\ to separate
% lines, just use ordinary line breaks like below.  It will
% appear on one line in the article, but will be used exactly
% as typed below to send a complimentary copy of the journal,
% so ensure that it is a complete postal address.
\address{Some Department,
         Other University,
         Address,
         Country}

% Additional authors done in the same way.

% If the author names are too long for the running head, use
% the following command to specify a shorter version:
%\shortauthors{DOE, SMITH \andname\ WILLIAMS}

% AMS 2000 Mathematics Subject Classification, ending with period.
% List one or several.
\classification{ABC123.}

% Keywords of the article, usually singular; no leading caps; ending with period.
\keywords{homology, homotopy.}

% Abstract comes before maketitle
\begin{abstract}
% Abstract text, no more than 200 words.
% Avoid bibliographic references and complicated mathematics.
\end{abstract}

% Leave these items like this, and the journal will fill them in.
\received{Month Day, Year}   % receive date (for example: October 11, 1999)
\revised{Month Day, Year}    % date of revision; omit, if no revision;
                             % if multiple revisions, separate by commas
\published{Month Day, Year}  % publish date
\submitted{Name of Editor}  % Name of Journal's Editor, who handled Article 
\volumeyear{2008} % Volume Year
\volumenumber{10} % Volume Number 
\issuenumber{1}   % Issue Number
\startpage{1}     % PageNumber of first page
\webaddress{http://intlpress.com/HHA/v10/n1/a?}
% If copyright is retained by author, comment this out:

\maketitle

% Text of Document.  Use constructs such as \section, \subsection,
% \begin{theorem} ... \end{theorem}, etc.

\section{Introduction}

This is the introduction.  It contains a displayed equation:
\[
  a + b = c .
\]

\begin{theorem}
A true statement.
\end{theorem}

\begin{proof}
This is the proof.
\end{proof}

\end{document}

Class Options

The format is always single column 10pt, for a fixed page size.

This option redefines the \le and \leq commands to use the form that amssymb calls \leqslant. The original form is still available as \oldleq. (Similar changes for greater than or equals.)

Front Matter

Standard article class uses one command, \author to specify all authors and all addresses. This makes specifying multiple authors inconvenient and so this class, in common with most other journal class files, abandons this in favour of having each author specified in separate \author commands.

\author{full name}

Each author is specified by such a command. The optional argument is for compatibility with classes that place author names in the running head. It is currently ignored by this class. (As it is intended for on screen viewing, it uses a `one sided' layout.)

\email{email address}

Each author may optionally be followed by this command to specify an email address.

\homepage{WWW address}

Each author may optionally be followed by this command to specify a homepage address.

\address{Full Postal Address}

After each group of authors sharing a postal address, this command should be used.

\thanks{footnote text}

First page footnote may be specified using \thanks. Note that unlike the article class, this command should not be used inside the arguments of the \author or \address commands. Also note that such first page footnotes have no footnote mark. The text of the footnote should make it clear what is being referred to.

\keywords{comma separated keyword list}

The author may specify keywords of the article.

\classification{comma separated classification list}

The author should give AMS 2000 Mathematics Subject Classifications.

\begin{abstract}
\end{abstract}

Article abstract. Must be specified before \maketitle.

LaTeX versions

This class file should work with any release of the LaTeX version 2e.

This class file will not work with the previous version of LaTeX, (LaTeX 2.09). LaTeX 2.09 is not supported and should no longer be used.
