DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/222/
 ">Rigidity of Roe-like algebras</a>\nby Alessandro Vignati (Université de
  Paris Cité) as part of Noncommutative geometry in NYC\n\n\nAbstract\nIn 
 the late 80s John Roe defined a family of C*-algebras capable of detecting
  coarse geometric properties of metric spaces in operator algebraic terms\
 ; these are called Roe-like algebras. It is fairly elementary to show that
  if two metric spaces look the same in coarse geometric terms\, that is\, 
 if they are (bijectively) coarsely equivalent\, then the associated Roe-li
 ke algebras are isomorphic. In this talk\, we investigate the converse imp
 lications\, trying to extract geometric information from algebraic data.\n
