Let H denote a finite-dimensional Hopf algebra with antipode S over a field β«ήβ¬ -. w We give a new proof of the fact, due to Oberst and Schneider Manuscripta Math. 8 Ε½ . x 1973 , 217α241 , that H is a symmetric algebra if and only if H is unimodular and S 2 is inner. If H is involutory and not sem

Some of the first examples of Hopf algebras described over a field k w x which are neither commutative nor cocommutative 13, 14 involve elements a and x which satisfy the relations β¬ a s a m a, β¬ x s x m a q 1 m x, and xa s qax Ε½ .

Let Bΰ » H be a crossed product algebra over an algebraically closed field, with H a finite dimensional Hopf algebra. We give an explicit equivalence between the category of finite dimensional Bΰ » H-modules whose restriction to B is a direct sum of copies of a stable irreducible B-module, and the categ
In the context of finite-dimensional cocommutative Hopf algebras, we prove versions of various group cohomology results: the QuillenαVenkov theorem on detecting nilpotence in group cohomology, Chouinard's theorem on determining whether a kG-module is projective by restricting to elementary abelian p
