On the notion of exact sequence: from Hopf algebras to tensor categories

Published 27 Mar 2020 in math.QA | (2003.12420v1)

Abstract: We present an overview of the notions of exact sequences of Hopf algebras and tensor categories and their connections. We also present some examples illustrating their main features; these include simple fusion categories and a natural question regarding composition series of finite tensor categories.
