A Categorical Approach to Imprimitivity Theorems for C*-Dynamical Systems
Siegfried Echterhoff, S. Kaliszewski, John Quigg +1
Imprimitivity theorems provide a fundamental tool for studying the representation theory and structure of crossed-product C*-algebras. In this work, we show that the Imprimitivity…
