To maintain the schedule, time limits will be strictly parentheses following the listings. The middle two digits, e.g., 897-20- enforced. 1136, refer to the Mathematical Reviews subject classification assigned For papers with more than one author, an asterisk follows the name of by the individual author. Groups of papers for each subject are listed the author who plans to present the paper at the meeting. chronologically in the Abstracts. The last one to four digits, e.g., 897-20- Papers flagged with a solid triangle (I) have been designated by the 1136, refer to the receipt number of the abstract; abstracts are further author as being of possible interest to undergraduate students. sorted by the receipt number within each classification.
