### Group actions on 2-categories

We study actions of discrete groups on 2-categories. The motivating examples are actions on the 2-category of representations of finite …

### A five-term exact sequence for Kac cohomology

We use relative group cohomologies to compute the Kac cohomology of matched pairs of finite groups. This cohomology naturally appears …

### On invariants of modular categories beyond modular data

We study novel invariants of modular categories that are beyond the modular data, with an eye towards a simple set of complete …

### Reflection fusion categories

We introduce the notion of a reflection fusion category, which is a type of a $G$-crossed category generated by objects of …

### On acyclic anyon models

Acyclic anyon models are non-abelian anyon models for which thermal anyon errors can be corrected. In this note, we characterize …
