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

摘要

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