Event description:

In this talk, we will discuss the K-theoretic Hall algebra of a surface, which generalizes the Grojnowski's and Nakajima's description of the cohomology of Hilbert schemes of points on surfaces. We will also discuss a wheel condition for the shuffle presentation of K theoretic Hall algebra, which originated from Feigin and Odesskii.
