Frobenius-Schur indicators for a class of fusion categories

Sonia Natale

Quantum Algebra

Abstract

We give an explicit description, up to gauge equivalence, of group-theoretical quasi-Hopf algebras. We use this description to compute the Frobenius-Schur indicators for group-theoretical fusion categories.
