Quasitriangular (G-cograded) multiplier Hopf algebras
Lydia Delvaux, Alfons Van Daele, Shuanhong Wang
We put the known results on the antipode of a usual quasitriangular Hopf algebra into the framework of multiplier Hopf algebras. We illustrate with examples which can not be obtain…

The Larson-Sweedler theorem for multiplier Hopf algebras
Alfons Van Daele, Shuanhong Wang
Any finite-dimensional Hopf algebra has a left and a right integral. Conversely, Larsen and Sweedler showed that, if a finite-dimensional algebra with identity and a comultiplicati…
