Editorial Information

To be published in the Proceedings, a paper must be correct, new, nontrivial, andsignificant. Further, it must be well written and of interest to a substantial number ofmathematicians. Piecemeal results, such as an inconclusive step toward an unprovedmajor theorem or a minor variation on a known result, are in general not acceptablefor publication. Proceedings Editors solicit and encourage publication of worthy papersof length not exceeding 10 published pages. Published pages are the same size as thosegenerated in the style files provided for AMS-LATEX or AMS-TEX .

Very short notes not to exceed two printed pages are also accepted, and appear underthe heading Shorter Notes. Items deemed suitable include an elegant new proof of animportant and well-known theorem, an illuminating example or counterexample, or a newviewpoint on familiar results. New results, if of a brief and striking character, might alsobe acceptable, though in general a paper which is merely very short will not be suitablefor the Shorter Notes department.

As of July 31, 1998, the backlog for this journal was approximately 11 issues. Thisestimate is the result of dividing the number of manuscripts for this journal in the Provi-dence office that have not yet gone to the printer on the above date by the average num-ber of articles per issue over the previous twelve months, reduced by the number of issuespublished in four months (the time necessary for editing and composing a typical issue).

A Consent to Publish and Copyright Agreement is required before a paper will bepublished in this journal. After a paper is accepted for publication, the Providence officewill send out a Consent to Publish and Copyright Agreement to all authors of the paper.By submitting a paper to this journal, authors certify that the results have not been sub-mitted to nor are they under consideration for publication by another journal, conferenceproceedings, or similar publication.

Information for Authors

Initial submission. Two copies of the paper should be sent directly to the appropriateEditor and the author should keep a copy.

The first page of an article must consist of a descriptive title, followed by an abstract

that summarizes the article in language suitable for workers in the general field (algebra,analysis, etc.). The descriptive title should be short, but informative; useless or vaguephrases such as “some remarks about” or “concerning” should be avoided. The abstract

should be at least one complete sentence, and at most 150 words. Included with thefootnotes to the paper, there should be the 1991 Mathematics Subject Classification rep-resenting the primary and secondary subjects of the article. This may be followed by a listof key words and phrases describing the subject matter of the article and taken from it. Alist of classifications may be found in the annual index of Mathematical Reviews, publishedwith the December issue starting in 1990. Journal abbreviations used in bibliographies arealso listed in the latest Mathematical Reviews annual index. The classifications and thejournal abbreviations are accessible from e-MATH via the World Wide Web through theURL http : //www.ams.org/publications/. When the manuscript is submitted, authorsshould supply the editor with electronic addresses if available. These will be printed afterthe postal address at the end of each article.

Electronically prepared manuscripts. The AMS encourages electronically pre-pared manuscripts, with a strong preference for AMS-LATEX. To this end, the Societyhas prepared AMS-LATEX author packages for each AMS publication. Author packagesinclude instructions for preparing electronic manuscripts, the AMS Author Handbook, sam-ples, and a style file that generates the particular design specifications of that publicationseries. Articles properly prepared using the AMS-LATEX style file automatically providehypertext linking to the bibliography and other elements of the article for searching elec-tronically on the World Wide Web. Because linking must often be added manually toelectronically prepared manuscripts in other forms of TEX, using AMS-LATEX also reducesthe amount of technical intervention once the files are received by the AMS. This resultsin fewer errors in processing and saves the author proofreading time. AMS-LATEX papers

also move more efficiently through the production stream, helping to minimize publishingcosts.

AMS-LATEX is the highly preferred format of TEX, but author packages are also availablein AMS-TEX. Those authors who make use of these style files from the beginning of thewriting process will further reduce their own efforts. Manuscripts prepared electronicallyin LATEX or plain TEX are normally not acceptable due to the high amount of technical timerequired to insure that the file will run properly through the AMS in-house productionsystem. LATEX users will find that AMS-LATEX is the same as LATEX with additionalcommands to simplify the typesetting of mathematics, and users of plain TEX should havethe foundation for learning AMS-LATEX.

Authors may retrieve an author package from e-MATH via the World Wide Webthrough the URL http : //www.ams.org/tex/ or via FTP to ftp.ams.org (login asanonymous and enter username as password). The author package can also be obtained freeof charge by sending e-mail to pub@ams.org (Internet) or from the Publication Division,American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248. When re-questing an author package, please specify AMS-LATEX or AMS-TEX, Macintosh or IBM(3.5) format, and the publication in which your paper will appear. Please be sure toinclude your complete mailing address.

At the time of submission, authors should indicate if the paper has been prepared usingAMS-LATEX or AMS-TEX and provide the Editor with a paper manuscript that matchesthe electronic manuscript. The final version of the electronic manuscript should be sentto the Providence office immediately after the paper has been accepted for publication.The author should also send the final version of the paper manuscript to the Editor, whowill forward a copy to the Providence office. Editors will require authors to send theirelectronically prepared manuscripts to the Providence office in a timely fashion. Electron-ically prepared manuscripts can be sent via e-mail to pub-submit@ams.org (Internet) oron diskette to the Electronic Prepress Department, American Mathematical Society, P.O.Box 6248, Providence, RI 02940-6248. When sending a manuscript electronically, pleasebe sure to include a message indicating in which publication the paper has been accepted.No corrections will be accepted electronically. Authors must mark their changes on theirproof copies and return them to the Providence office. Complete instructions on how tosend files are included in the author package.

Electronic graphics. Figures may be sent to the AMS in an electronic format. TheAMS recommends that graphics created electronically be saved in Encapsulated PostScript(EPS) format. This includes graphics originated via a graphics application as well asscanned photographs or other computer-generated images.

If the graphics package used does not support EPS output, the graphics file should besaved in one of the standard graphics formats—such as TIFF, PICT, GIF, etc.—ratherthan in an application-dependent format. Graphics files sent in an application-dependentformat are not likely to be used. No matter what method was used to produce the graphic,it is necessary to provide a paper copy to the AMS.

Authors using graphics packages for the creation of electronic art should also avoid theuse of any lines thinner than 0.5 points in width. Many graphics packages allow the userto specify a “hairline” for a very thin line. Hairlines often look acceptable when proofedon a typical laser printer. However, when produced on a high-resolution laser imagesetter,hairlines become nearly invisible and will be lost entirely in the final printing process.

Screens should be set to values between 15% and 85%. Screens which fall outside ofthis range are too light or too dark to print correctly.

TEX files available. Beginning with the January 1992 issue of the Bulletin and theJanuary 1996 issues of Transactions, Proceedings, Mathematics of Computation, and theJournal of the AMS, TEX files can be downloaded from e-MATH, starting from URLhttp : //www.ams.org/journals/. Authors without Web access may request their files atthe address given below after the article has been published. For Bulletin papers publishedin 1987 through 1991 and for Transactions, Proceedings, Mathematics of Computation, and

the Journal of the AMS papers published in 1987 through 1995, TEX files are availableupon request for authors without Web access by sending e-mail to file-request@ams.org

or by contacting the Electronic Prepress Department, American Mathematical Society,P.O. Box 6248, Providence, RI 02940-6248. The request should include the title of thepaper, the name(s) of the author(s), the name of the publication in which the paper hasor will appear, and the volume and issue numbers if known. The TEX file will be sentto the author making the request after the article goes to the printer. If the requestorcan receive Internet e-mail, please include the e-mail address to which the file shouldbe sent. Otherwise please indicate a diskette format and postal address to which a diskshould be mailed. Note: Because TEX production at the AMS sometimes requires extrafonts and macros that are not yet publicly available, TEX files cannot be guaranteed torun through the author’s version of TEX without errors. The AMS regrets that it cannotprovide support to eliminate such errors in the author’s TEX environment.

Any inquiries concerning a paper that has been accepted for publication should be sentdirectly to the Electronic Prepress Department, American Mathematical Society, P.O. Box6248, Providence, RI 02940-6248.
