(Hopf) Algebra Automorphisms of the Hopf Algebra
Abstract
In this article, we completely determine the group of algebra automorphisms for the two-parameter Hopf algebra. As a result, the group of Hopf algebra automorphisms is determined for as well. We further characterize all the derivations of the subalgebra and calculate its first degree Hochschild cohomology group. © 2013 Copyright Taylor and Francis Group, LLC.
