Title: Categorified Hall algebras and their representations versus categorified Nakajima operators
Date (JST): Thu, Mar 28, 2024, 15:30 - 17:00
Place: Seminar Room A
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.
