Parent event: 
MPIM Topology Seminar
In this talk I will explain higher Morita categories of $E_n$-algebras and bimodules and
discuss dualizability therein (joint with Owen Gwilliam). Important examples are a
3-category of fusion categories and a 4-category of modular tensor categories, which are
related to the Turaev-Viro and Reshetikin-Turaev TFTs. I will give an overview of existing
results and discuss why these do not suffice for Reshetikin-Turaev theories.
