Bulletin (New Series) of the American Mathematical Society

This journal is devoted to articles of the following types:

Research-Expository Surveys

These are, by definition, papers that present a clear and insightful exposition of signif-icant aspects of contemporary mathematical research. Gibbs lectures, Progress in Math-ematics lectures, and retiring presidential addresses will be included in this section.

Research Reports

These are brief, timely reports on important mathematical developments. They arenormally solicited and often written by a disinterested expert.

Book Reviews

Book Reviews are accepted for publication by invitation only. Unsolicited manuscriptswill not be considered.

Editorial Information

As of June 30, 2000, the backlog for this journal was approximately 0 issues.This estimate is the result of reducing the number of manuscripts for this journalin the Providence office that have not yet gone to the printer on the above date bythe number of articles assigned to issues to be published in four months (the timenecessary for editing and composing a typical issue). In an effort to make articlesavailable as quickly as possible, articles are posted to e-MATH individually soonafter proof is returned from authors and before appearing in an 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 Providenceoffice will send a Consent to Publish and Copyright Agreement to all authors of thepaper. By submitting a paper to this journal, authors certify that the results havenot been submitted to nor are they under consideration for publication by anotherjournal, conference proceedings, or similar publication.

Information for Authors

Initial submission. For Research-Expository Surveys and Research Reports,copies of the manuscript—three copies for Surveys and four copies for Reports—may be submitted to Professor Donald G. Saari, Department of Mathematics. Mul-tipurpose Science and Technology Building, University of California, Irvine, Irvine,CA 92697-3875. Manuscripts may also be submitted to other members of the re-spective Editorial Boards, with a copy of the cover letter and of the manuscript alsosent to Professor Donald G. Saari. The author should keep one copy. Research-Expository Surveys and Research Reports can also be submitted electronically inAMS-LATEX or AMS-TEX to [email protected]. IF an editor is agreeable, anelectronic manuscript prepared in TEX or LATEX may be submitted by pointing toan appropriate URL on a preprint or e-print server.

For Research-Expository Surveys and Research Reports, the first page mustconsist of a descriptive title, followed by an abstract that summarizes the articlein language suitable for workers in the general field (algebra, analysis, etc.). Thedescriptive title should be short but informative; useless or vague phrases such as“some remarks about” or “concerning” should be avoided. The abstract shouldbe a brief technical description of the new material. Then, for Research Reports

there should be an introductory section addressed to nonexperts describing themotivation, background, and significance of the results announced. Following thestatement of results, there should be a sketch of proofs that may be addressed toexperts. Included with the footnotes in each paper should be the 2000 Mathe-

matics Subject Classification representing the primary and secondary subjects ofthe article. The classifications are accessible from www.ams.org/msc/. The listof classifications is also available in print starting with the 1999 annual index ofMathematical Reviews. The Mathematics Subject Classification footnote may befollowed by a list of key words and phrases describing the subject matter of thearticle and taken from it. Journal abbreviations used in bibliographies are listedin the latest Mathematical Reviews annual index. The series abbreviations arealso accessible from www.ams.org/publications/. To help in preparing and ver-ifying references, the AMS offers MR Lookup, a Reference Tool for Linking, atwww.ams.org/mrlookup/. When the manuscript is submitted, authors should sup-ply the editor with electronic addresses if available. These will be printed after thepostal address at the end of each article.

For Book Reviews the first page must include the title of the book being reviewed;the name(s) of the author(s); publisher; city of publication; year of publication;number of pages, including front matter; price if known; and ISBN. There shouldalso be a footnote with the 2000 Mathematics Subject Classification representingthe primary and secondary subjects of the book under review. The classificationsare accessible from www.ams.org/msc/ and are also available in print starting withthe 1999 annual index of Mathematical Reviews. To help in preparing and ver-ifying references, the AMS offers MR Lookup, a Reference Tool for Linking, atwww.ams.org/mrlookup/.

Electronically prepared manuscripts. The AMS encourages electronicallyprepared manuscripts, with a strong preference for AMS-LATEX. To this end, theSociety has prepared AMS-LATEX author packages for each AMS publication. Au-thor packages include instructions for preparing electronic manuscripts, the AMS

Author Handbook, samples, and a style file that generates the particular designspecifications of that publication series. Articles properly prepared using the AMS-LATEX style file and the \label and \ref commands automatically enable extensiveintra-document linking to the bibliography and other elements of the article forsearching electronically on the Web. Because linking must often be added manu-ally to electronically prepared manuscripts in other forms of TEX, using AMS-LATEXalso reduces the amount of technical intervention once the files are received by theAMS. This results in fewer errors in processing and saves the author proofreadingtime. AMS-LATEX papers also move more efficiently through the production stream,helping to minimize publishing costs.

AMS-LATEX is the highly preferred format of TEX, but author packages are alsoavailable in AMS-TEX. Those authors who make use of these style files from thebeginning of the writing process will further reduce their own efforts. Manuscriptsprepared electronically in LATEX or plain TEX are normally not acceptable due tothe high amount of technical time required to insure that the file will run properlythrough the AMS in-house production system. LATEX users will find that AMS-LATEX is the same as LATEX with additional commands to simplify the typesettingof mathematics, and users of plain TEX should have the foundation for learningAMS-LATEX.

Authors may retrieve an author package from e-MATH starting from www.ams.

org/tex/ or via FTP to ftp.ams.org (login as anonymous, enter username as

password, and type cd pub/author-info). The AMS Author Handbook and theInstruction Manual are available in PDF format following the author packageslink from www.ams.org/tex/. The author package can also be obtained free ofcharge by sending email to [email protected] (Internet) or from the Publication Divi-sion, American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248.When requesting an author package, please specify AMS-LATEX or AMS-TEX, Mac-intosh 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 preparedusing AMS-LATEX or AMS-TEX and provide the Editor with a paper manuscriptthat matches the electronic manuscript. The final version of the electronic man-uscript should be sent to the Providence office immediately after the paper hasbeen accepted for publication. The author should also send the final version of thepaper manuscript to the Editor, who will forward a copy to the Providence office.Editors will require authors to send their electronically prepared manuscripts to theProvidence office in a timely fashion. Electronically prepared manuscripts can besent via email to [email protected] (Internet) or on diskette to the ElectronicPrepress Department, American Mathematical Society, P.O. Box 6248, Providence,RI 02940-6248. When sending a manuscript electronically, please be sure to includea message indicating in which publication the paper has been accepted. No cor-rections will be accepted electronically. Authors must mark their changes on theirproof copies and return them to the Providence office. Complete instructions onhow to send files are included in the author package.

Electronic graphics. Comprehensive instructions on preparing graphics areavailable at www.ams.org/jourhtml/graphics.html. A few of the major require-ments are given here.

Submit files for graphics as EPS (Encapsulated PostScript) files. This includesgraphics originated via a graphics application as well as scanned photographs orother computer-generated images. If this is not possible, TIFF files are acceptableas long as they can be opened in Adobe Photoshop or Illustrator. No matter whatmethod was used to produce the graphic, it is necessary to provide a paper copy tothe AMS.

Authors using graphics packages for the creation of electronic art should alsoavoid the use of any lines thinner than 0.5 points in width. Many graphics packagesallow the user to specify a “hairline” for a very thin line. Hairlines often lookacceptable when proofed on a typical laser printer. However, when produced on ahigh-resolution laser imagesetter, hairlines become nearly invisible and will be lostentirely in the final printing process.

Screens should be set to values between 15% and 85%. Screens which fall outsideof this range are too light or too dark to print correctly. Variations of screens withina graphic should be no less than 10%.

Secure manuscript tracking on the Web and via email. Authors can tracktheir manuscripts through the AMS journal production process using the personalAMS ID and Article ID printed in the upper right-hand corner of the Consentto Publish form sent to each author who publishes in AMS journals. Access tothe tracking system is available from www.ams.org/mstrack/ or via email sent [email protected]. To access by email, on the subject line of the messagesimply enter the AMS ID and Article ID. To track more than one manuscript byemail, choose one of the Article IDs and enter the AMS ID and the Article IDfollowed by the word all on the subject line. An explanation of each production

step is provided on the Web through links from the manuscript tracking screen.Questions can be sent to [email protected].

TEX files available. Beginning with the January 1992 issue of the Bulletin andthe January 1996 issues of Transactions, Proceedings, Mathematics of Computation,and the Journal of the AMS, TEX files can be downloaded from e-MATH, startingfrom www.ams.org/journals/. Authors without Web access may request their filesat the address given below after the article has been published. For Bulletin paperspublished 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 emailto [email protected] or by contacting the Electronic Prepress Department,American Mathematical Society, P.O. Box 6248, Providence, RI 02940-6248. Therequest should include the title of the paper, the name(s) of the author(s), thename of the publication in which the paper has or will appear, and the volume andissue numbers if known. The TEX file will be sent to the author making the requestafter the article goes to the printer. If the requestor can receive Internet email,please include the email address to which the file should be sent. Otherwise pleaseindicate a diskette format and postal address to which a disk should be mailed.Note: Because TEX production at the AMS sometimes requires extra fonts andmacros that are not yet publicly available, TEX files cannot be guaranteed to runthrough 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.

Inquiries. Any inquiries concerning a paper that has been accepted for pub-lication that cannot be answered via the manuscript tracking system mentionedabove should be sent to [email protected] or directly to the Electronic Pre-press Department, American Mathematical Society, P.O. Box 6248, Providence, RI02940-6248.

Research-Expository Surveys

This section is intended for reasonably broad expository surveys of a currentlyactive area of mathematical research. To stress this fact, the name of the sectionhas been changed from “Research-Expository Papers” to “Research-Expository Sur-veys”. The level of exposition is expected to be such that a graduate student—or aresearch mathematician from a remote area—will be able to read an article in orderto get an overview of a subject. A well-written article will include motivating prob-lems and examples, some indication of the historical development of the subject,and of course the results and open problems that make it an interesting and excit-ing area of mathematics. In most cases proofs should be at most briefly sketched,and there should be a good bibliography whose main aim should be helping thosewishing to pursue the subject further. Usually Research-Expository Surveys willbe at most 40 pages long.

Certain of the Society’s Lecture Series, including the Gibbs Lectures, Collo-quium Lectures, and Progress in Mathematics Lectures, traditionally appear in theResearch-Expository Surveys, and those invited to give these lectures are informedof this tradition and of the above guidelines. Research-Expository Surveys are alsofrequently solicited by the Editorial Board, but unsolicited manuscripts are alsoencouraged; in particular, those invited to give invited hour addresses at meetingsof the Society should consider writing up their lecture in a manner that meetsthe requirements of the preceding paragraph and submitting their manuscripts forconsideration by the Editorial Board for the Research-Expository Surveys.

Research Reports

A Research Report is a timely, short (4–8 pages) report on a recent accomplish-ment in mathematical research. It should be written so as to be understandableby mathematicians who are not experts in the subject matter of the Report. Thecontext giving significance to the research being reported on should be made clear,and the consequences or potential consequences should be described. Usually onlythe barest hint of the methods of proof should be given, although elements of theproof which are novel should be included. In any case, references should be given sothat an interested reader can find the details. It is expected that Research Reportswill frequently be written by specialists other than the individuals immediatelyinvolved in the research.

Research Reports are normally solicited by the “Editorial Board for ResearchReports”. They cordially invite suggestions for topics and reporters. Unsolicitedmanuscripts, submitted to a member of the Editorial Board for Research Reports,will also be considered.

The American Mathematical Society’s electronic-only journal,Electronic Research Announcements of the AMS (ERA-AMS), is available on the World Wide Web at www.ams.org/era.

ERA-AMS publishes high-quality research announcements ofsignificant advances in all branches of mathematics. Authorsmay submit manuscripts to any editor. All papers are reviewed,and the entire Editorial Board must approve the acceptance ofany paper. Papers are posted as soon as they are accepted andprocessed by the AMS.
