Computing the Frobenius-Schur indicator for abelian extensions of Hopf algebras
Yevgenia Kashina, Geoffrey Mason, Susan Montgomery
In this paper we show that for an important class of non-trivial Hopf algebras, the Schur indicator is a computable invariant. The Hopf algebras we consider are all abelian extensi…

Self-dual modules of semisimple Hopf algebras
Yevgenia Kashina, Yorck Sommerhaeuser, Yongchang Zhu
We prove that, over an algebraically closed field of characteristic zero, a semisimple Hopf algebra that has a nontrivial self-dual simple module must have even dimension. This gen…
