Top matter

The input format and content of the top matter can be best understood by examining the first part of the sample file DIMACS-L.tex, up through the \begin{document} instruction.

The top matter includes both elements that must be input by the author and a few that are provided automatically. The author names and the title that are to appear in the running heads should be input between square brackets as an option to the \author and \title commands, respectively. The full names and title should be used unless they require too much space; in that event, abbreviated forms should be substituted. In the top matter, the title is input in caps and lowercase and will be set that way. The author names should be input in caps and lowercase; they will automatically be set in all caps.

For each author an address should be input. If the current address is different than the address where the research was carried out then both addresses are given with the current address second and coded as indicated in this sample file. Following these addresses, an address for electronic mail should be given, if one exists. Note that no abbreviations are used in addresses, and complete addresses for each author should be entered in the order that names appear on the title page. Addresses are considered part of the top matter but are set at the end of the paper, following the references.

Subject classifications (\subjclass) and acknowledgments (\thanks) are part of the top matter and will appear as footnotes at the bottom of the first page. Subject classifications (\subjclass) are required. Use the 1991 Mathematics Subject Classification that appears in annual indexes of Mathematical Reviews beginning in 1990. (The two-digit code from the Contents is not sufficient.)

Use \thanks for the footnotes that appear on the first page. It is generally desirable not to attach footnote numbers or symbols to titles or author names used as headings. If a footnote applies to only one author then include this information in the footnote.

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