Abstract
We introduce the notions of self-dual (graded) Hopf algebras and of structurally simple (graded) Hopf algebras. We prove that the self-dual Hopf algebras are structurally simple and provide a construction of self-dual Hopf algebras. Finally, we classify the self-dual quotients of the form TB (M)/I, where TB (M) is a path algebra with a graded Hopf algebra structure, and I is a graded admissible Hopf ideal.
