Query: Categorical perspectives in noncommutative duality   Noncommutative duality for C*-dynamical systems is a vast generalization of
Pontryagin duality for locally compact abelian groups. In this series of
lectures, we give an introduction to the categorical aspects of this duality,
focusing primarily on Landstad duality for actions and coactions of locally
compact groups.
