Let k be a field and let A n ω be the Taft's n 2 -dimensional Hopf algebra. When n is odd, the Drinfeld quantum double D A n ω of A n ω is a ribbon Hopf algebra. In a previous paper we constructed an n 4 -dimensional Hopf algebra H n p q which is isomorphic to D A n ω if p = 0 and q = ω -1 , and stu
Let R: M ® M ~ M ® M be a solution to the quantum Yang-Baxter equation, where M is a finite-dimensional vector space over a field k. It was shown that R can be derived from a left H-module structure and a right H-comodule structure on M for some bialgebra H over k (see [FRT, Mjl, Y]). The module and
We present some results about the representation ring of the quantum double of a finite group over fields of arbitrary characteristic. We give a direct sum decomposition of this representation ring into ideals involving Green rings of subgroups. Given characters of such Green rings, we construct cha
