On fusion 2-categories

Abstract: I will revisit and categorify concepts from the theory of fusion categories — including idempotent completeness and semi-simplicity, ultimately leading to a notion of `fusion 2-category’. I will highlight structural similarities and differences between fusion 1- and 2-categories and discuss several concrete examples. If time permits, I will discuss the role of fusion 2-categories as a natural building block for 4-dimensional topological field theories.

Quantum Groups Seminar [QGS]

Series comments: This seminar aims to bring together experts in the area of quantum groups. The seminar topics will cover the theory of quantum groups and related structures in a large sense: Hopf algebras, operator algebras, q-deformations, higher categories and related branches of noncommutative mathematics.

The zoom link will be distributed by mail, so please join the mailing list if you are interested in attending the seminar.

Organizers: Rubén Martos, Frank Taipe*, Makoto Yamashita
