Reading seminar in algebraic geometry.
Spring 2018. Topics in algebraic geometry

This semester the reading seminar will study various topics in algebraic geometry. Each speaker will present a paper they are reading for their own research projects which is of general interest to algebraic geometers.

The seminar will consist of talks by faculty followed by talks by graduate students. We will attempt to make the seminar accessible to everyone.

The seminar will meet on Friday afternoons, 2:30--3:30PM in LGRT 1234.
