The summer and annual meetings are joint meetings of the Mathematical Association of America and the American Mathematical Society. The meeting dates which fall rather far in the future are subject to change: this is particularly true of meetings to which no numbers have yet been assigned. Programs of the meetings will appear in the issues indicated below. First and supplementary announcements of the meetings will have appeared in earlier issues. ABSTRACTS OF PAPERS presented at a meeting of the Society are published in the journal Abstracts of papers presented to the American Mathematical Society in the issue corresponding to that of the Notices which contains the program of the meeting. Abstracts should be submitted on special forms which are available in many departments of mathematics and from the office of the Society. Abstracts must be accompanied by the $15 processing charge. Abstracts of papers to be presented at the meeting must be received at the headquarters of the Society in Providence. Rhode Island, on or before the deadline given below for the meeting. Note that the deadline for abstracts for consideration for presentation at special sessions is usually three weeks earlier than that specified below. For additional information consult the meeting announcements and the list of organizers of special sessions.

Requests for a change of address should a/ways include the member or subscriber code and preferably a copy of the entire mailing label. Members are reminded that U. S. Postal Service change-of-address forms are not adequate for this purpose. since they make no provision for several important items of information which are essential for the AMS records. Suitable forms are published from time to time in the Notices of the American Mathematical Society (e.g. October 1984, page 728). Send change of address notices to the Society at Post Office Box 6248, Providence, Rl 02940. [Notices of the American Mathematical Society is published seven times a year (January. March, June. August, October, November, December) by the American Mathematical Society at 201 Charles Street, Providence. Rl 02904. Second class postage paid at Providence. Rl and additional mailing offices. POSTMASTER: Send address change notices to Membership and Sales Department, American Mathematical Society. P. 0. Box 6248, Providence. Rl 02940.) Publication here of the Society's street address. and the other information in brackets above. is a technical requirement of the U. S. Postal Service. All correspondence should be mailed to the Post Office Box, NOT the street address. Members are strongly urged to notify the Society themselves of address changes, since reliance on the postal service change-of-address forms is liable to cause delays in processing such requests in the AMS office.
