Quantum groups and the cohomology of quiver varieties (Eric Vasserot, Université Pierre et Marie Curie-Université Paris Diderot)
22.02.2017 14:00 – 15:30
We'll first give an introduction to Nakajima's quiver varieties and their cohomology and/or K-theory.
Next, when the quiver is of finite type, we'll construct the action of yangians/quantum affine algebras on these cohomology groups.
Finally, when the quiver is of Jordan type, we'll construct the action of the elliptic Hall algebra.
