Abstract:

Let G be a group and kG be the group algebra of G  over a field k. It is well known that the kG-Hopf  bimodule category kGkG MkGkG is

equivalent to the direct category ∏C ∈ K(G) MkZu(C) . For any Hopf quiver Q=(G, r), the kG-Hopf bimodule structures on the arrow comodule kQ1 can be derived from the right kZu(C)-module structures on u(C)(kQ1)1. In this paper, the author discusses the isomorphic classification of Hopf path coalgebra kQc and the structures of Hopf subalgebra of kG[kQ1] of kQc in case G is a cyclic group and G is a Klein quaternion group, respectively.
