SUMMARY
We study the higher Frobenius-Schur indicators of modules over semisimple Hopf algebras, and relate them to other invariants as the exponent, the order, and the index. We prove various divisibility and integrality results for these invariants. In particular, we prove a version of Cauchy's theorem for semisimple Hopf algebras. Furthermore, we give some examples that illustrate the general theory.Kashina, Yevgenia is the author of 'On Higher Frobenius-schur Indicators ', published 2006 under ISBN 9780821838860 and ISBN 0821838865.
