The aim of this talk is to study the automorphism groups of Hopf k-algebras induced by Hopf quivers and linear characters. Let G be a group with Schurian ramification r such that the corresponding Hopf quiver is connected, c and t be linear characters of G. We prove that the graded automorphism group of Hopf k-algebra H(G, r, c, t) is the wreath product of k* by the automorphism group of the datum (G, r, c, t).
