Abstract: |
As the terminology suggests, categorified Hall algebras are a form of "categorification" of (2-dimensional) cohomological Hall algebras. In the first part of the talk, I will describe them and an approach to construct their categorified representations. If time permits, I will compare this framework with the quest of categorifying Nakajima type operators. |
