Frobenius-Schur Indicators for Subgroups and the Drinfel'd Double of Weyl Groups
Robert Guralnick, Susan Montgomery
If G is a finite group and k is a field, there is a natural construction of a Hopf algebra over k associated to G, the Drinfel'd double D(G). We prove that if G is any finite real…
Indecomposable set-theoretical solutions to the Quantum Yang-Baxter Equation on a set with prime number of elements
Pavel Etingof, Robert Guralnick, Alexander Soloviev
In this paper we show that all indecomposable nondegenerate set-theoretical solutions to the Quantum Yang-Baxter equation on a set of prime order are affine, which allows us to giv…
Biperfect Hopf Algebras
Pavel Etingof, Shlomo Gelaki, Robert Guralnick +1
Recall that a finite group is called perfect if it does not have non-trivial 1-dimensional representations (over the field of complex numbers C). By analogy, let us say that a fini…
