Partial (Co)actions of multiplier Hopf algebras: Morita and Galois theories
Abstract
In this work, we deal with partial (co)actions of multiplier Hopf algebras on not necessarily unital algebras. Our main goal is to construct a Morita context relating the coinvariant algebra RcoA̲ with a certain subalgebra of the smash product R#Â. Besides that, we present the notion of partial Galois coaction, which is closely related to this Morita context.
