On the classification of Rokhlin flows
In this talk, I will explain a classification theory of Rokhlin flows on C*algebras, which in part is inspired by a similar recent theory in von Neumann algebras due to Masuda and Tomatsu. The Rokhlin property for flows on C*algebras is an important concept introduced by Kishimoto, who eventually conjectured that every Kirchberg algebra carries a unique Rokhlin flow up to cocycle conjugacy. The emphasis of this talk will be the positive solution to his conjecture. I will attempt to outline (in reasonable detail) how to compare two Rokhlin flows on the same C*algebra as approximate cocycle perturbations of each other, which had long been known to be the missing piece towards the conjecture. If time permits, I may address how one can push the classification beyond the case of Kirchberg algebras.
