Title：Representations of the small quasi-quantum group

Abstract：In this talk, we give the representations of the small quantum group and the small quasi-quantum group respectively, where q is a primitive n-th root of unity and n>2 is odd. All finite dimensional indecomposable -modules are described and classified. Moreover, the decomposition rules for the tensor products of -modules are given. Finally, we describe the structures of the projective class ring and the Green ring . We show that is isomorphic to a subring of and the stable Green rings and are isomorphic.
