Proceedings of the American Mathematical Society
This journal is devoted entirely to research in pure and applied mathematics.
Editorial Policy
To be published in the Proceedings, a paper must be correct, new, nontrivialand significant. Further, it must be well written and of interest to a substantialnumber of mathematicians. Piecemeal results, such as an inconclusive steptoward an unproved major theorem or a minor variation on a known result,are in general not acceptable for publication. Proceedings Editors shall solicit,and encourage publication of, worthy papers of length not exceeding 15 typed
pages.Very short notes not to exceed two printed pages are also accepted, and
appear under the heading Shorter notes. Items deemed suitable include anelegant new proof of an important and well-known theorem, an ¿Illuminatingexample or counterexample, or a new viewpoint on familiar results. New results,if of a brief and striking character, might also be acceptable, though in generala paper which is merely very short will not be suitable for the Shorter notes
department.
On January 23, 1979, the Council of the American Mathematical Societyabolished blind refereeing as a policy for the Proceedings, but decided that anyauthor who so requests and who provides a blind copy of a manuscript will havethe manuscript refereed blind.
Two copies of a manuscript should be submitted. If blind refereeing isintended, one should be complete and one blind, and then the latter will be sentto the referee without disclosure of the author's name or institution.
SUBSCRIPTION INFORMATION. PROCEEDINGS OF THE AMERICAN MATHEMATI-CAL SOCIETY is published monthly. Subscription prices for Volumes 102-104 (1988) are $401list; $321 institutional member; $241 individual member. A late charge of 10% of the subscription
price will be imposed upon orders received from nonmembers after January 1 of the subscription
year. Subscribers outside the United States and India must pay a postage surcharge of $25: sub-scribers in India must pay a postage surcharge of $38. Expedited delivery to destinations in NorthAmerica—$30; elsewhere—$40. Combination paper and microfiche subscription prices are $533list; $426 institutional member. Microfiche of each issue will be mailed the fastest way possiblebefore the camera copy is sent to the printer. Microfilm subscriptions may be purchased fromUniversity Microfilms International, 300 North Zeeb Road, Ann Arbor, Michigan 48106.
BACK NUMBER INFORMATION. Back number prices per volume are for Volumes 1-89,$113 list, $90 institutional; for Volumes 90-92, $129 list; $103 institutional member; for Volumes93-95, $173 list; $138 institutional member; for Volumes 96-98, $191 list; $153 institutionalmembers; for Volumes 99-101, $202 list; $162 institutional member.

Manuscript Information
1. Articles submitted for publication should be typewritten, double spaced,
and no more than 15 (8|" x 11") pages long. The Manual for Authors, available
from the Society, should be consulted for symbols and style conventions. Authors
should take the greatest possible care in preparing the original manuscript. Hand
drawn symbols are satisfactory, if clearly done; directions to the printer should be
included where necessary on a separate sheet. Authors must keep complete copies of
their manuscripts, and editors will acknowledge receipt. To encourage the submis-
sion of manuscripts in electronic form using T£X and the AjvlS-T^i macro package,the Executive Committee of the Council has adopted a policy that allows for ac-
celerating 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.
2. 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. The abstract should be at least one complete sentence, and at most
150 words. Included with the footnotes to the paper, but placed before the first
footnote, there should be first the 1980 Mathematics Subject Classification (1985Revision) representing 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 the numbers may be found in the annual
subject index of Mathematical Reviews, published with the December issue starting
in 1984.
3. A Copyright Transfer Agreement is required before a paper will be publishedin the Proceedings. A copy of the form is sent with the acknowledgement of receipt
of manuscript from the Providence office of the Society. Authors are urged to
return the forms immediately to prevent delays in processing and publishing of the
manuscript.
OFFPRINTS AND ADDRESS CHANGES. Any inquiries concerning a paper which has beenaccepted for publication, including information regarding offprints or changes of address for mailing
proof, should be sent directly to the Editorial Department, American Mathematical Society, P.O.
Box 6248, Providence, Rhode Island 02940.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 acceptedfor publication.
BACKLOG. 150 pages. Papers currently being accepted by the editors will be published in
12-14 months.COPYING AND REPRINTING. Individual readers of this publication, and nonprofit li-
braries acting for them are permitted to make fair use of the material, such as to copy an article
for use in teaching or research. Permission is granted to quote brief passages from this publicationin reviews provided the customary acknowledgement of the source is given.
Republication, systematic copying, or multiple reproduction of any material in this publication
(including abstracts) is permitted only under license from the American Mathematical Society. Re-
quests for such permission should be addressed to the Executive Director, American Mathematical
Society, P.O. Box 6248, Providence, Rhode Island 02940.The appearance of the code on the first page of an article in this journal indicates the copyright
owner's consent for copying beyond that permitted by Sections 107 or 108 of the U.S. Copyright
Law, provided that the fee of $1.00 plus $.25 per page for each copy be paid directly to Copy-
right Clearance Center, Inc., 21 Congress Street, Salem, Massachusetts 01970. This consent doesnot extend to other kinds of copying, such as copying for general distribution, for advertising or
promotion purposes, for creating new collective works, or for resale.
