Exact sequences of Frobenius tensor categories
arXiv:2303.14687
Abstract
Given a tensor functor between tensor categories and , we give criteria that, under certain assumptions, the Frobeniusness of or implies the Frobeniusness of the other one. We also give an affirmative answer to Natale's question asking if the class of Frobenius tensor categories is closed under exact sequences.
