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

in Journal of pure and applied algebra

Abstract

In this paper, we study the tensor product structure of the category of finite dimensional modules over Drinfeld doubles of Taft Hopf algebras. Tensor product decomposition rules for all finite dimensional indecomposable modules are explicitly given.
