Resumen:
We classify finite-dimensional complex pointed Hopf algebras withgroup of group-like elements isomorphic to A_5. We show that any pointedHopf algebra with infinitesimal braiding associated with the conjugacy classof pi in A_n is infinite-dimensional if the order of is pi odd except for pi = (1 2 3)in A_4. We also study pointed Hopf algebras over the dihedral groups.
