DESCRIPTION:Speakers: Federico Vigulo (Universität Göttingen)\n\nObersem
 inar Differentialgeometrie\nWith every proper metric space are associated 
 C*-algebras of special geometric importance (Roe algebras)\, originally de
 fined for index-theoretic considerations. It is a simple observation that 
 metric spaces that are coarsely equivalent give rise to isomorphic C*-alge
 bras. Much more surprisingly\, the converse also holds: a C*-rigidity Theo
 rem shows that spaces with isomorphic Roe algebras must be coarsely equiva
 lent. This establishes a strong connection between the categories of coars
 e spaces and C*-algebras. In this introductory talk I aim to properly intr
 oduce the C*-rigidity question and illustrate the roadmap of the proof of 
 rigidity.\n\nhttps://math-events.uni-bonn.de/event/1490/
