Journal overview: This journal is devoted to research articles in all areas of pure and applied mathematics. To be published in the Transactions, a paper must be correct, new, and significant. 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. Papers of less than 15 printed pages that meet the above criteria should be submitted to the Proceedings of the American Mathematical Society. Published pages are the same size as those generated in the style files provided for AMS-LaTeX or AMS-TeX.

Submission information: Information can be found on the journal's Submission for Peer Review page.

Copying and reprinting: Material in this journal may be reproduced by any means for educational and scientific purposes without fee or permission with the exception of reproduction by services that collect fees for delivery of documents and provided that the customary acknowledgment of the source is given. This consent does not extend to other kinds of copying for general distribution, for advertising or promotional purposes, or for resale. Requests for permission for commercial use of material should be addressed to the Acquisitions Department, American Mathematical Society, 201 Charles Street, Providence, RI 02904-2294 USA. Requests can also be made by email to reprint-permission@ams.org .

Excluded from these provisions is material in articles for which the author holds copyright. In such cases, requests for permission to use or reprint should be addressed directly to the author(s). Copyright ownership is indicated in the notice in the lower right-hand corner of the first page of each article.

Publishing cycle: Transactions of the American Mathematical Society is published monthly with articles posted individually to the AMS website before appearing in an issue. Beginning in January 1996, Transactions is accessible from http://www.ams.org/tran/ .

Indexing and archiving notes: This journal is indexed in Mathematical Reviews, Zentralblatt MATH, Science Citation Index®, Science Citation Index--Expanded, ISI Alerting Services, CompuMath Citation Index®, and Current Contents®, Physical, Chemical & Earth Sciences.  This journal is archived in Portico.

Subscriptions: Subscriptions to this journal can be obtained through the AMS Bookstore . Subscriptions and orders can also be addressed to the American Mathematical Society, P.O. Box 845904, Boston, MA 02284-5904 USA. All orders must be accompanied by payment. Other correspondence should be addressed to American Mathematical Society, 201 Charles Street, Providence, RI 02904-2294 USA.

Backlog information: As of October 31, 2008, the backlog for this journal was approximately 11 issues. The backlog may depend upon the subject area of the paper. This estimate is the result of dividing the number of manuscripts for this journal in the Providence office that have not yet gone to the printer on the above date by the average number 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). In an effort to make articles available as quickly as possible, articles are posted to the AMS website individually after proof is returned from authors and before appearing in an issue.

Inquiries: Any inquiries concerning a paper that has been accepted for publication that cannot be answered via the manuscript tracking system should be sent to tran-query@ams.org or directly to the Electronic PrePress Department, American Mathematical Society, 201 Charles Street, Providence, RI 02904-2294 USA.
