Slightly degenerate categories and $\mathbb{Z}$-modular data

Quantum Algebra 2023-11-07 v3 Category Theory

Abstract

Given a slightly degenerate fusion category C\mathcal{C}, we explain how it naturally gives rise to a Z-modular data. We do not restrict to spherical categories and work with pivotal categories instead. Finally, we give an interpretation in this framework of the Bonnaf\'e-Rouquier categorification of the Z\mathbb{Z}-modular datum associated to non trivial family of the cyclic complex reflection group.
