TRANSACTIONS OF THE AMERICAN MATHEMATICAL SOCIETY

THIS JOURNAL is devoted entirely to research in pure and applied mathematics, and in-

cludes, 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 double-spaced,

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

To encourage the submission of manuscripts in electronic form using TgX and the AmS-T^X macro

package, the Executive Committee of the Council has adopted a policy that allows for accelerating

the publication date of such manuscripts by as much as 20 weeks, which is approximately equal to

the time normally needed by the Society for copyediting, typesetting, and proofreading an average

manuscript.

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

be published in 14-16 months.

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.
