Berkeley Arithmetic Geometry and Number Theory Seminar
Spring 2019

This is a weekly RTG seminar funded by NSF and organized by Daniel Bragg, David Corwin, Martin Olsson, and Sug Woo Shin. This webpage is maintained by Daniel Bragg.


The seminar is scheduled at 3:10-5:00 every Monday in 748 Evans. It consists of two 50-minute talks: a pre-talk (3:10-4:00) and an advanced talk (4:10-5:00), with a 10-minute break (4:00-4:10) between them. The advanced talk is a regular formal presentation about recent research results to general audiences in arithmetic geometry and number theory; the pre-talk (3:10-4:00) is to introduce some prerequisites or background for the advanced talk to audiences consisting of graduate students.

Spring 2019 Schedule (3:10-5:00pm Monday, 748 Evans)

Titles and abstracts may appear first on the math department calendar.
