Title:
Cohomological Hall algebras and affine quantum groups

Speaker:
Yaping Yang

Abstract:
It is a classical theorem of Ringel that the Hall algebra of a quiver Q is isomorphic to the positive half of the quantum enveloping algebra of the Lie algebra associated to Q. In this talk, I will talk about an affine analogue of the above theorem.
