New York Number Theory Seminar

In January 1982, Number Theorists in New York City and its environs began meeting regularly at the Graduate Center of the City University. The location was convenient to all parts of the city as well as to major transportation hubs. The original organizers were Harvey Cohn, David Chudnovsky, Gregory Chudnovsky and Melvyn B. Nathanson. Harvey Cohn has retired, but Nathanson is now based in the City University and able to act as host of the seminar.

Proceedings of the Seminar have been published by Springer-Verlag, originally in the Lecture Notes in Mathematics series

More recent reports appear as individual volumes, with the simple title Number Theory, and the names of the editors of the volume on the cover.

This page was first developed in the Fall of 2000. Schedules by semester are available.

Current Semester

The Graduate Center is currently located at 365 Fifth Avenue, between 34th and 35th Streets. The Ph.D. program in mathematics is located on the fourth floor. The seminar has met on Thursday afternoons for several years. In the Spring 2012 semester the seminar will met Thursdays from 3:00 to 4:00 in room 4419. More details will be posted in the department common area on the fourth floor. Current information on all seminars can be found in the Seminar Page of the Graduate Center Mathematics Department.
