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…
The cointegral theory of weak multiplier Hopf algebras
Nan Zhou, Tao Yang
In this paper, we introduce and study the notion of cointegrals in a weak multiplier Hopf algebras . A cointegral is a non-zero element in the multiplier algebra …
A Duality Theorem for Weak Multiplier Hopf Algebra Actions
Nan Zhou, Shuanhong Wang
The main purpose of this paper is to unify the theory of actions of Hopf algebras, weak Hopf algebras and multiplier Hopf algebras to one of actions of weak multiplier Hopf algebra…
