6 Simple Hopf Algebras and Deformations of Finite Groups
We show that certain twisting deformations of a family of supersolvable groups are simple as Hopf algebras. These groups are direct products of two generalized dihedral groups. Examples of this construction arise in dimensions 60 and pq, for prime numbers p, q with q|p − 1. We also show that certain twisting deformation of the symmetric group is simple as a Hopf algebra. On the other hand, we p...
متن کاملAdditive Deformations of Hopf Algebras
Additive deformations of bialgebras in the sense of Wirth are deformations of the multiplication map of the bialgebra fulfilling a compatibility condition with the coalgebra structure and a continuity condition. Two problems concerning additive deformations are considered. With a deformation theory a cohomology theory should be developed. Here a variant of the Hochschild cohomology is used. The...

متن کاملNormal Hopf Subalgebras in Cocycle Deformations of Finite Groups
We determine necessary and sufficient conditions, in grouptheoretical terms, for a Hopf subalgebra in a cocycle deformation of a finite group to be normal.
متن کاملBialgebra Cohomology, Pointed Hopf Algebras, and Deformations
We give explicit formulas for maps in a long exact sequence connecting bialgebra cohomology to Hochschild cohomology. We give a sufficient condition for the connecting homomorphism to be surjective. We apply these results to compute all bialgebra two-cocycles of certain Radford biproducts (bosonizations). These two-cocycles are precisely those associated to the finite dimensional pointed Hopf a...
