Michigan – Arithmetic Geometry Initiative – Columbia

MAGIC is an online seminar starting in May. The topic is arithmetic geometry, broadly construed to include parts of algebraic geometry and number theory, focusing on concrete problems.

The seminar is organized by Wei Ho (University of Michigan) and Will Sawin (Columbia University).

MAGIC meets Thursdays, 1:30 pm - 2:30 pm EDT, 12:30 pm - 1:30 pm CDT, on Zoom (password is the order of the finite simple group A6).
That is 10:30 am - 11:30 am PDT, 18:30 - 19:30 BST, and 19:30 - 20:30 CET.
