报告摘要：
We shall review the classification of graded Hopf algebra structures on path coalgebras (and dually quantization of path algebras) in connection with the framework of Hopf algebra constructions on a Hopf bimodule over a Hopf algebra. We conclude a path coalgebra admits a graded Hopf algebra structure iff its quiver is a Hopf quiver. We will also elaborate on how Hopf bimodules support this classification: the category of Hopf bimodules over a group algebra is equivalent to a product of right module categories, which ensures the completeness of our classification and links quiver combinatorics to Hopf algebra constructions.
