Seminar on Topics in Arithmetic, Geometry, Etc.

STAGE is a seminar in algebraic geometry and number theory, featuring speakers talking about work that is not their own. Talks will be at a level suitable for graduate students. Everyone is welcome. In Spring 2013, we are planning a series of talks on topics surrounding the recent progress on the Tate conjecture for K3 surfaces.
Meetings are held on Fridays, 5-6pm in MIT room 4-149, except as noted below.
To receive announcements by email, add yourself to the STAGE mailing list.
