Quiver Varieties


This course is an introduction to the study of quiver representations and the associated moduli problems. The first half of the course will be dedicated to a proof of Gabriel's theorem asserting that a connected quiver has a finite number of isomorphism classes of representations for every fixed dimension vector if and only if the underlying undirected graph is a simply laced Dynkin diagram.
After this, we will study the symplectic and (hyper)-Kahler approaches to studying moduli spaces of quiver representations.

Meeting place and time
