Preparation of Manuscripts

General Requirements

  • Abstract. All papers must contain a brief abstract. Please try to avoid displayed formulas and bibliographic references in the abstract. So that it can be compiled independents of the rest of the paper, the abstract should not contain custom macros.
  • Subject classification. Papers should contain a subject classification in the usual format, with one or two primary classification numbers and, optionally, one or more secondary classification numbers. In the amsart LaTeX documentclass, the classification can be provided using the \subjclass{…} macro. (For examples using this construct, see the templates and sample files below.)
  • Running title. If the title is too long to be used as running title, please provide a short title. In LaTeX this can be accomplished using the \title macro as follows: \title[shorttitle]{fulltitle}.
  • Acknowledgments. Brief acknowledgments will be typeset as unnumbered footnotes on the title page. In the amsart LaTeX documentclass, this can be achieved with the \thanks{…} macro. (Note that the amsart class does not allow explicit footnotes to authors or titles.) Longer acknowledgments will be typeset as unnumbered subsections at the end of the paper, or the end of the introductory section.

LaTex Templates and Sample Files

IJM is typeset in LaTeX, using a variant of the amsart documentclass, so papers prepared in that format are easiest to process. You may wish to use, or consult, one of the following LaTeX templates and sample LaTeX files.

  • Basic LaTeX template. A basic LaTeX template.
  • Enhanced LaTeX template. A slightly customized version of the basic template with a provision for theorem and equation numbering by section (e.g., Theorem 1.1, Corollary 1.2, (1.1), (1.2), etc.).
  • Sample file. A complete LaTeX file of an article published in IJM.

Additional Guidelines for Papers in LaTex

The following simple guidelines will help significantly reduce the time and cost involved in processing papers. Most of these guidelines are not IJM specific but simply reflect good LaTeX practices.

  • Documentclass/documentstyle. Use of the standard documentclasses for journal articles, either the AMS article class “amsart” or the standard LaTeX “article” class–i.e., \documentclass{amsart} or \documentclass{article}. (In LaTeX 2.09, the old version of LaTex, replace \documentclass by \documentstyle.)
  • Page dimensions. To achieve the correct page dimensions, add the following commands to the preamble:\setlength{\textheight}{43pc}
    \setlength {\textwidth}{28pc}. Do not use other commands that change page dimensions (such as oddsidemargin or hoffset, or baselinestretch), since such commands may interfere with the above settings and will likely have to be removed when processing the paper. Also, remove any options to the “\documentclass” command that change the font size or page dimensions, such as [11 pt] or [a4paper].
  • Bibliography. Set references using \bibitem and the thebibliography environment, using a format similar to that used by AMS journals. If you have a bibtex database, use amsalpha or amsplain as bibliography style to generate the bibitem entries.
  • Avoid manual formatting. Do not use commands such as
    • \centerline{1. Introduction}
    • {\bf Theorem 1.} {\it …}
    • \par\noindent{\it Proof.}

    To format sections, theorems, proofs, etc., use appropriate LaTex constructs:

    • \section{Introduction}
    • \begin{theorem} … \end{theorem} (along with a \newtheorem declaration)
    • \begin{proof} … \end{proof}

    Similarly, avoid explicit spacing commands like \bigskip, \newline or \\ (except in multiline displays), or \noindent. LaTeX commands such as \end{proof} or \section automatically create an appropriate amount of space. Manual coding of theorems, proofs, section headings, etc., will have to be removed by us and replaced by corresponding LaTeX constructs; this is a laborious and time-consuming task. Excessive manual formatting may increase the time it takes us to process a paper by an order of magnitude.

    • Packages. Standard packages, loaded with \usepackage{…}, are fine, if they are needed in the paper. Some useful packages are graphicx (for graphics inclusion), amssymb, or amscd (for commutative diagrams).
    • Pictures. Electronically generated graphics should be provided as eps (encapsulated postscript) files.
    • Special note for users of Scientific Workplace (TCI). Scientific Workplace can create LaTeX files, but for the files to be compatible with a standard LaTeX environment, they must be saved as portable LaTeX files; otherwise, the files created require proprietary macros and cannot be used outside the SW.

    Guidelines for Papers in AmsTeX and Plain TeX

    Papers in AmsTeX will be converted by us to LaTeX. As with LaTeX papers, manual formatting should be avoided, and appropriate amstex/amsppt constructs should be used, such as the following:

    • \title … \endtitle
    • \author .. \endauthor
    • \head … \endhead
    • \proclaim … \endproclaim
    • \demo … \enddemo
    • \ref … \endref

    We use an automated process that can convert properly formatted AmsTeX papers to LaTeX, with little or no additional markup required. To achieve the correct page dimensions, use no \magnification and specify the following in the preamble, after \documentstyle{amsppt}:
    \pageheight{43pc}
    \pagewidth{28pc}

    For papers in plain TeX, specify the page dimensions with the following commands:
    \vsize43pc \hsize28pc. Do not use a magnification.

    LaTeX Tips

    The following is a home-grown (and growing) list of tips for using LaTeX more efficiently, borne out of experience with processing papers for IJM. The tips are geared toward typesetting mathematical journal articles and are not IJM specific.
