A Ardizzoni, M Beattie, C Menini - Journal of Algebra, 2010 - Elsevier
Let H be a Hopf algebra over a field K of characteristic 0 and let A be a bialgebra or Hopf

Deformation by cocycles of pointed Hopf algebras over non-abelian groups
GA García, M Mastnak - arXiv preprint arXiv:1203.0957, 2012 - arxiv.org
We introduce a method to construct explicitly multiplicative 2-cocycles for bosonizations of
Nichols algebras B (V) over Hopf algebras H. These cocycles arise as liftings of H-invariant …

Finite generation of some cohomology rings via twisted tensor product and Anick resolutions
Over a field of prime characteristic p> 2, we prove that the cohomology rings of some pointed
Hopf algebras of dimension p 3 are finitely generated. These are Hopf algebras arising in …

On twisting of finite-dimensional Hopf algebras
In this paper we study the properties of Drinfeld's twisting for finite-dimensional Hopf
algebras. We determine how the integral of the dual to a unimodular Hopf algebra H …

Hopf algebra deformations of binary polyhedral groups
J Bichon, S Natale - Transformation Groups, 2011 - Springer
We show that semisimple Hopf algebras having a self-dual faithful irreducible comodule of
dimension 2 are always obtained as abelian extensions with quotient Z2. We prove that …
