Indecomposable decomposition of tensor products of modules over Drinfeld Doubles of Taft algebras

Abstract

In this paper, we study the tensor structure of category of finite dimensional representations of Drinfeld quantum doubles $D(H_n(q))$ of Taft Hopf algebras $H_n(q)$. Tensor product decomposition rules for all finite dimensional indecomposable modules are explicitly given.
