The Drinfel'd double for group-cograded multiplier Hopf algebras

L. Delvaux, A. Van Daele

Let $G$ be any group and let $K (G)$ denote the multiplier Hopf algebra of complex functions with finite support in $G$ . The product in $K (G)$ is pointwise. The comultiplication on…

Hopf C*-algebras

Stefaan Vaes, Alfons Van Daele

In this paper we introduce the notion of a Hopf C*-algebra and construct the counit and antipode. A Hopf C*-algebra is a C*-algebra with comultiplication satisfying some extra cond…
