Computing indicators of Radford algebras

Published 18 Apr 2017 in math.RT | (1704.05363v1)

Abstract: We compute higher Frobenius-Schur indicators of Radford algebras in positive characteristic and find minimal polynomials of these linearly recursive sequences. As a result of Kashina, Montgomery and Ng, we obtain gauge invariants for the monoidal categories of representations of Radford algebras.
