Title: Unimodular H-comodule algebras

Abstract: Unimodular Hopf algebras H are an interesting subclass of Hopf algebras which can be used to construct invariants of 3-manifolds. For instance, semisimple Hopf algebras are unimodular. In this talk, inspired by applications to TQFTs, we will introduce the notion of unimodular H-comodule algebras. We will also provide examples and discuss some open questions.
