Abstract

Given a tensor functor between tensor categories C\mathcal{C} and D\mathcal{D}, we give criteria that, under certain assumptions, the Frobeniusness of C\mathcal{C} or D\mathcal{D} 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.
