Study group on Geometric Invariant Theory

This working seminar takes place on Fridays from 3 to 4 pm in Room 7395 at the CUNY Graduate Center. All are welcome.

Our goal is to study Geometric Invariant Theory, and variation of GIT quotients in particular.
Time permitting we'll look at applications of GIT to representation theory.
