Federico Vigolo: Markov operators and ghost projections. Oberseminar C*-Algebren

Tuesday, 01.12.2020 15:15 per ZOOM: Link to Zoom info

Mathematik und Informatik

The aim of this talk is to explain some of the tools that are necessary to prove that warped cones violate the coarse Baum-Connes conjecture. In the first part, I will introduce the notion of Markov kernel and explain a few basic facts concerning reversible Markov processes. In the second part I will explain how they are used to show that the Roe algebra of warped cones associated with strongly ergodic actions have an abundance of non-compact ghost projections.

Because of the Corona crisis, the lectures will be given as online lectures via zoom (or other video conference software). Please contact us by sending a message to our secretary Elke Enning, if you are interested to participate, so that we can send you an invitation for the lectures.
