Geometry, Symmetry and Physics Seminar

The K-theoretic Hall algebra of a surface and the Feigin-Odesskii wheel conditions

Yu Zhao, MIT

Location:  Serin Lab E372
Date & time: Thursday, 24 October 2019 at 11:00AM - 12:00PM

 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.
