TRANSACTIONS OF THE AMERICAN MATHEMATICAL SOCIETYTHIS JOURNAL is devoted entirely to research in pure and applied mathematics, and includes, in

general, longer papers than those in the PROCEEDINGS. Papers should be at least 16 typed pages in

length.

PREPARATION OF THE MANUSCRIPT. All papers should be typewritten doublerspaced, and

two copies should be sent to the appropriate editor. The author should keep a complete copy.

FORM OF MANUSCRIPT. The first page should consist of a descriptive title, followed by an

abstract which 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. Also avoid proper names unless mathematical

usage associates them with the work. The abstract should be at least one complete sentence, and at most

300 words, with the upper limit primarily for longer papers. Included with the footnotes to your paper,but placed before the first footnote, there should be first the 1980 Mathematics Subject Classification

(1985 Revision) representing the primary and secondary subjects of the article, which 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 the

numbers may be found in the annual subject index of Mathematical Reviews, published with the

December issue starting in 1984.

SUBMISSION OF MANUSCRIPT. See the back of this journalCOPYRIGHT TRANSFER AGREEMENT. The signing of a Copyright Transfer Agreement is a

requirement for publication.GALLEY PROOF. When a paper with more than one author has been accepted for publication, only

one set of galley proof will be sent. Joint authors should, therefore, indicate on the original manuscript

which of them should receive galley proof in the event that the manuscript is accepted for publication.PUBLICATION CHARGES. The research journals of the American Mathematical Society carry a

page charge of $50.00 per page to help defray the cost of publication. The amount is charged to the

institution or to a contract supporting the research reported in the published paper. The publication

charge policy of the United States Federal Council for Science and Technology (FCST) is reported on

page 112 of the February, 1975 issue of the NOTICES of the American Mathematical Society. In no case

is the author personally responsible for paying the page charge, nor is acceptance of his paper for

publication dependent upon payment of the page charge.

BACKLOG. 100 pages. Two-thirds of the papers currently being accepted by the editors will be

published in 10-12 months.

CAL SOCIETY is published monthly. Subscription prices for Volumes 299-304 (1987) are $643.00 list;

MEMOIRS OF THE AMERICAN MATHEMATICAL SOCIETYThis bimonthly journal is devoted to research in pure and applied mathematics of much the same

nature as appears in TRANSACTIONS. An issue consists of one or more separately bound research

tracts for which the author(s) has provided reproduction copy. Prior to 1975 this was publishedas a monograph series. The editorial committee is identical with that for the TRANSACTIONS

so that papers intended for publication in this series should be addressed to one of the editors.
