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

**1052**: 11 articles from 1982.**1135**: 11 articles from 1983 and 1984.**1240**: 16 articles from 1984 and 1985.**1383**: 14 articles from 1985 through 1988.

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.

- 13 articles from 1989 through 1990 (ISBN 0-387-97670-1).
- 22 articles from 1991 through 1995 (ISBN 0-387-94826-0).
- 16 articles from 1995 through 2003 (ISBN 0-387-40655-7).

This page was first developed in the Fall of 2000. Schedules by semester are available. Links to pages between Fall 2000 and Spring 2010 can be found on the Fall 2010 page.

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 2018 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.
