Coactions of weak multiplier Hopf algebras
Nan Zhou
In this article, we investigate the notion of a coaction for a weak multiplier Hopf algebra. We show that there is a duality for actions and coactions of weak algebraic quantum gro…

An algebraic framework for the Drinfeld double based on infinite groupoids
Nan Zhou, Shuanhong Wang
The Drinfeld double associated to the weak multiplier Hopf (-) algebra pairing is constructed. We show that the Drinfeld double is again a weak…
