John Quigg: Cocycle approach to duality

C*-algebra seminar talk by John Quigg (Arizona State University)

Title: Cocycle approach to duality

Abstract: We propose a new approach to "Landstad duality" (a way to recover an action or coaction up to isomorphism from the crossed product), using crossed-product duality and cocycles. The method avoids delicate averaging processes that are a feature of existing proofs. Joint with S. Kaliszewski and Magnus Landstad.
