Abstract
|
|
|
|
| In this paper we study subHopfalgebras of graded Hopf algebra structures on a path coalgebra kQ(c). We prove that a Hopf structure on some subHopfquivers can be lifted to a Hopf structure on the whole Hopf quiver. If Q is a Schurian Hopf quiver, then we classified all simple-pointed subHopfalgebras of a graded Hopf structure on kQ(c). We also prove a dual Gabriel theorem for pointed Hopf algebras.
