Kopsachei lis (WWU Münster. Germany) as part of Functional analysis and operator al gebras in Athens\n\n\nAbstract\nRegularity properties of C*-algebras are v ital for classification theory. In the C*-setting\, finite nuclear dimensi on\, tensorial absorption of the Jiang--Su algebra and strict comparison s et the stage for Elliott's classification programme\; these properties are known to be tightly related\, as the (to a large extent confirmed) Toms-- Winter conjecture predicts. On the dynamical side\, analogues of these hav e been introduced for group actions\, and it is not yet quite clear how th ese relate to the regularity properties of the crossed product. In this ta lk\, we introduce a comparison type property in the context of Cartan suba lgebras and study its relations to regularity properties of the ambient C* -algebra\, and of the underlying dynamics\, when the inclusion arises from a topological dynamical system. \nThis talk is based on joint work (in pr ogress) with Wilhelm Winter.\n LOCATION:https://researchseminars.org/talk/AthensFAOA/61/ END:VEVENT END:VCALENDAR
