Further, it must be well written and of interest to a substantial number of mathematicians. Piecemeal results, such as an inconclusive step toward an unproved major theorem or a minor variation on a known result, are in general not acceptable for publication. Proceedings Editors solicit and encourage publication of worthy papers of length not exceeding 10 published pages. Published pages are the same size as those A generated in the style files provided for AMS-LTEX or AMS-TEX . Very short notes not to exceed two printed pages are also accepted, and appear under the heading Shorter Notes. Items deemed suitable include an elegant new proof of an important and well-known theorem, an illuminating example or counterexample, or a new viewpoint on familiar results. New results, if of a brief and striking character, might also be acceptable, though in general a paper which is merely very short will not be suitable for the Shorter Notes department. As of August 31, 1996, the backlog for this journal was approximately 8 issues. This estimate 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 issues published 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 be published in this journal. By submitting a paper to this journal, authors certify that the results have not been submitted to nor are they under consideration for publication by another journal, conference proceedings, or similar publication. Information for Authors Initial submission. Two copies of the paper should be sent directly to the appropriate Editor 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 vague phrases 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 the footnotes 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 list of key words and phrases describing the subject matter of the article and taken from it. A list of classifications may be found in the annual index of Mathematical Reviews, published with the December issue starting in 1990. Journal abbreviations used in bibliographies are also listed in the latest Mathematical Reviews annual index. The classifications and the journal abbreviations are accessible from e-MATH via the World Wide Web through the URL http : //www.ams.org/committee/publications/mr-info.html or via FTP to e-math.ams.org (login as anonymous and enter username as password). The classifica- tions are available as a browsable list and the journal abbreviations are available through a search tool. When the manuscript is submitted, authors should supply the editor with electronic addresses if available. These will be printed after the postal address at the end of each article. Electronically prepared manuscripts. The AMS encourages submission of elec- A tronically prepared manuscripts, with a strong preference for AMS-LTEX submissions. A To this end, the Society has prepared AMS-LTEX author packages for each AMS publica- tion. Author packages include instructions for preparing electronic manuscripts, the AMS Author Handbook, samples, and a style file that generates the particular design specifi- A cations of that publication series. Articles properly prepared using the AMS-LTEX style file automatically provide hypertext linking to the bibliography and other elements of the article for searching electronically on the World Wide Web. Because linking must often A be added manually to submissions in other forms of TEX, using AMS-LTEX also reduces the amount of technical intervention once the files are received by the AMS. This results A in fewer errors in processing and saves the author proofreading time. AMS-LTEX papers also move more efficiently through the production stream, helping to minimize publishing costs. A AMS-LTEX is the highly preferred format of TEX, but author packages are also available in AMS-TEX. Those authors who make use of these style files from the beginning of the writing process will further reduce their own efforts. Electronically submitted manuscripts A prepared in LTEX or plain TEX are normally not acceptable due to the high amount of technical time required to insure that the file will run properly through the AMS in-house A A A production system. LTEX users will find that AMS-LTEX is the same as LTEX with additional commands to simplify the typesetting of mathematics, and users of plain TEX A should have little difficulty learning AMS-LTEX. Authors may retrieve an author package from e-MATH via the World Wide Web through the URL http : //www.ams.org/tex/ or via FTP to e-math.ams.org (login as anonymous and enter username as password). The author package can also be obtained free of charge by sending e-mail to [email protected] (Internet) or from the Publication Divi- sion, American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248. When A requesting an author package, please specify AMS-LTEX or AMS-TEX, Macintosh or IBM (3.5) format, and the publication in which your paper will appear. Please be sure to include your complete mailing address. At the time of submission, authors should indicate if the paper has been prepared using A AMS-LTEX or AMS-TEX and provide the Editor with a paper manuscript that matches the electronic manuscript. The final version of the electronic manuscript should be sent to 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, who will forward a copy to the Providence office. Editors will require authors to send their electronically prepared manuscripts to the Providence office in a timely fashion. Electron- ically prepared manuscripts can be sent via e-mail to [email protected] (Internet) or on diskette to the Electronic Prepress Department, American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248. When submitting an electronic manuscript, please be 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 their proof copies and return them to the Providence office. Complete instructions on how to submit files are included in the author package. Electronic graphics. Figures may be submitted to the AMS in an electronic format. The AMS recommends that graphics created electronically be saved in Encapsulated Post- Script (EPS) format. This includes graphics originated via a graphics application as well as scanned photographs or other computer-generated images. If the graphics package used does not support EPS output, the graphics file should be saved in one of the standard graphics formats—such as TIFF, PICT, GIF, etc.—rather than in an application-dependent format. Graphics files submitted in an application- dependent format 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 the use of any lines thinner than 0.5 points in width. Many graphics packages allow the user to specify a “hairline” for a very thin line. Hairlines often look acceptable when proofed on 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 of this range are too light or too dark to print correctly. TEX files available. Beginning with the January 1992 issue of the Bulletin and the January 1996 issues of Transactions, Proceedings, Mathematics of Computation, and the Journal of the AMS, TEX files can be downloaded from e-MATH, starting from URL http : //www.ams.org/journals/. Authors without Web access may request their files at the address given below after the article has been published. For Bulletin papers published in 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 available upon request for authors without Web access by sending e-mail to [email protected] 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 the paper, the name(s) of the author(s), the name of the publication in which the paper has or will appear, and the volume and issue numbers if known. The TEX file will be sent to the author making the request after the article goes to the printer. If the requestor can receive Internet e-mail, please include the e-mail address to which the file should be sent. Otherwise please indicate a diskette format and postal address to which a disk should be mailed. Note: Because TEX production at the AMS sometimes requires extra fonts and macros that are not yet publicly available, TEX files cannot be guaranteed to run through the author’s version of TEX without errors. The AMS regrets that it cannot provide support to eliminate such errors in the author’s TEX environment. Any inquiries concerning a paper that has been accepted for publication should be sent directly to the Electronic Prepress Department, American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248. Editors Authors are requested to send papers directly to the appropriate Editor (the one whose area of responsibility and expertise, as described below, most closely approximates the subject field of the manuscript). Only when in doubt about an appropriate Editor, should manuscripts be sent to the Coordinating Editor responsible for the area in mathematics most closely connected to the paper. If in doubt about the area, send the manuscript to the Managing Editor, to whom all other communication about the journal should also be addressed. (All addresses should include the line “Department of Mathematics”, unless another department is indicated.)
