SUMMARY:C*-rigidity: a bridge between coarse geometry and C*-algebras - Fe

DESCRIPTION:With every proper metric space are associated C*-algebras of s
 pecial geometric importance (Roe algebras)\, originally defined for index-
 theoretic considerations. It is a simple observation that metric spaces th
 at are coarsely equivalent give rise to isomorphic C*-algebras\, and recen
 tly we could prove that the converse also holds. Namely\, a C*-rigidity Th
 eorem shows that spaces with isomorphic Roe algebras must be coarsely equi
 valent. This establishes a strong connection between the categories of coa
 rse spaces and C*-algebras. In this introductory talk I aim to properly in
 troduce the C*-rigidity question and illustrate the roadmap of the proof o
 f rigidity.
