Lectures by Andrei Okounkov (Columbia),

Tuesday, March 17, 5-7pm, 105 Shillman, Thursday and Friday, March 19 and 20, 010 Behrakis, 4-6pm. Here is a map (Shillman is building 30 and Behrakis is building 26).

Topic: Computations in quantum K-theory. This deals with ramifications of a nice short paper which offers a new approach to Geometric representation theory and computes quantum cohomology of Nakajima quiver varieties.

Background reading/watching:

1) Equivariant K-theory, a reference is Chriss-Ginzburg book, Chapter 5.

2) Some understanding of quantum cohomology will be useful. Possible source -- lectures of Barbara Bolognese, Michael Viscardi, Ryan Mickler, Eric Riedl from this seminar.

3) This is NOT a prerequisite but understanding connections between quantum cohomology and representation theory may be useful as well. Last year, Andrei gave a series of lectures in Princeton on this topic, videos are available. There are also notes of Mike McBreen's talks, see here and here.

Lectures will be preceded by a graduate student seminar in the first week of March.
