Representations Parameterized by a Pair of Characters

David E. Radford, Hans-Jürgen Schneider

Let $U$ and $A$ be algebras over a field $k$ . We study algebra structures $H$ on the underlying tensor product $U \otimes A$ of vector spaces which satisfy $(u{\otimes}a)(u'{\otime…

On the irreducible representations of a class of pointed Hopf algebras

David E. Radford, Hans-Jürgen Schneider

We parameterize the finite-dimensional irreducible representations of a class of pointed Hopf algebras over an algebraically closed field of characteristic zero by dominant charact…

Biproducts and Two-Cocycle Twists of Hopf Algebras

David E. Radford, Hans-Jürgen Schneider

Let $H$ be a Hopf algebra with bijective antipode over a field $k$ and suppose that $R{#}H$ is a bi-product. Then $R$ is a bialgebra in the Yetter--Drinfel'd category ${}_H^H{\math…
