Instructions for using the hjm class file for preparing papers for publication in the Houston Journal of Mathematics. Copyright David H. Wagner April 1, 1997 updated April 11, 1997 The hjm.cls provides a latex2e class, "hjm". This class is based on the amsart class that is provided with the amslatex package. Thus, all of the amslatex equation and alignment macros are available as a part of the hjm class. Documentation for amslatex can be found in the file amsldoc.tex, which should be available in your local installation. Use of this file also requires a working knowledge of latex2e. However these instructions will attempt to provide you with enough information to get you started. 1. In the beginning... The first line of your tex file should be \documentclass{hjm} The body of the text begins with a line \begin{document} and ends with \end{document} At least superficially, Latex is a "structured programming language". This means that many commands, or "environments", start with a \begin command and end with an \end command, just like the document environment illustrated above. If you want to define your own macros you can enter them in between the \documentclass line and the \begin{document} line. You are strongly encouraged not to use plain tex \def commands, or related definition commands, to define your own macros. Instead, use Latex's \newcommand command. For example, my favorite is \newcommand{\p}[1]{\left(#1\right)} %parentheses. Using \newcommand will enable Latex to tell you when you have attempted to redefine an existing tex or Latex macro. If you really want to redefine an existing macro, use \renewcommand. You may also want to control the numbering of equations. If you do nothing, equations will be defined using single natural numbers in sequence throughout the whole document. I like the equations in section 3 to have the format 3.xx, so I use \numberwithin{equation}{section} With version 1.2, the hjm class now defines theoremstyles for theorems, lemmas, corollaries, propositions, definitions, and remarks. To use the predefined theoremstyles, use \begin{thm} \end{thm} Similarly, environments lem, cor, prop, dfn, rmk are defined for the other theoremstyles. Numbering for theorems, lemmas, corollaries, and propositions are all in a single sequence, numbered within sections of your paper, e.g., Theorem 3.1, Proposition 3.2, Lemma 3.3, Corallary 3.4. Definitions are numbered in a single sequence throughout the paper. Remarks are also numbered in a single sequence throughout the paper. If you have other mathematical statements that you wish to be numbered together with the theorems, put a statement like the following before the \begin{document} line. This line creates an environment "foobar" which is formatted like a Theorem, with the title "FooBar", and numbered with the theorems. \newtheorem{foobar}[thm]{FooBar} The Houston Journal of Mathematics intends to use the theoremstyles described above as the standard for theorems, lemmas, propositions, corollaries, definitions, and remarks. The Journal reserves the right to establish other standards for formatting and equation numbering in the future. 2. The body. After the \begin{document} line, you need to enter your title, author(s), author addresses, thanks for any funding, and e-mail address (if you so desire). You can also enter subject class and keywords. Anything of this nature that is provided in the amsart class is also available in the hjm class. The basis syntax for some of these items is: \title{Proof of the Riemann Hypothesis} \author{John Smith} \address{1234 Main Street\\ Wichita, KS 76543} \email{JSmith@aol.com} \author{Daisy Jones\\ 4321 Upton Blvd.\\ Dayton, OH 34567} \email{DJones@locker.org} \thanks{Research supported by NSF grant \#96-1234} \date{April 1, 1997} \abstract{In this paper we present a proof of the Rieamann hypothesis. Wow!} Note: If your abstract is placed before the title, then you have an old version of amslatex. Download a new package from CTAN ftp sites, or have your system administrator do so. Finally, end this "topmatter" stuff with \maketitle Now, you can *really* begin the body of the text, with \section{Introduction} %Or whatever you want to name the first %section This should get you started. You may, however, still need to learn Latex and amslatex. Good luck!
