DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/57/"
 >Traces on ultrapower C*-algebras</a>\nby Francesc Perera (Universitat Aut
 ònoma de Barcelona) as part of Noncommutative geometry in NYC\n\n\nAbstra
 ct\nEvery sequence of traces on a C*-algebra induces a limit trace on a fr
 ee ultrapower. I will discuss the natural question of characterizing when 
 this set of limit traces is dense\, and mention the use of techniques comi
 ng from the theory of Cuntz semigroups to obtain such a characterization. 
 This talk is based on joint work with Ramon Antoine\, Leonel Robert\, and 
 Hannes Thiel.\n
