Title: Cohomological Hall algebras, their representations, and Nakajima 
operators


Abstract: In the first part of the talk, I will give a brief 
introduction to the theory of 2d cohomological Hall algebras (COHAs), 
focusing on the example of COHAs of zero-dimensional sheaves on smooth 
surfaces. Additionally, I will describe certain geometric 
representations of these COHAs and introduce Nakajima type operators. In 
the second part of the talk, I will discuss a generalization and 
categorification of this framework.

All are welcome to attend.
