题目:REPRESENTATIONS OF DRINFELD DOUBLES OF RADFORD HOPF ALGEBRAS
摘要:In this article, we investigate the representations of the Drinfeld doubles D(Rmn(q)) of the Radford Hopf algebras Rmn(q) over an algebraically closed field k, where m > 1 and n > 1 are integers and q ∈ k is a root of unity of order n. Under the assumption char(k) - mn, all the finite dimensional indecomposable modules over D(Rmn(q)) are displayed and classified up to isomorphism. The Auslander Reiten sequences in the category of finite dimensional D(Rmn(q))-modules are also all displayed. It is shown that D(Rmn(q)) is of tame representation type. This is a joint work with Hua Sun.
