Orateur(s) Alessandro Vignati - IMJ-PRG,
Titre L'exposé est reporté à une date ultérieure - Uniform Roe algebras and rigidity, part II
Horaire15:10 à 16:10
RésumeThis talk is the second part of Farah's talk from two weeks ago. From a coarse metric space X one associates a C*-algebra known as the Uniform Roe algebra of X. This algebra has a canonical quotient called the Uniform Roe corona of X. We study the question of what information on spaces X and Y one can infer when the Uniform Roe coronas of X and Y are isomorphic, and how answers to this question depend on the set theoretical axioms in play. This is joint work with Bruno Braga and Ilijas Farah.
