C*-algebra and Cuntz semigroup,   Wang, Kun,   UPR, Rio Piedras,  , 1 February, 2012,   10:00 a.m. A-207


Recent examples due first to Rordam and later Toms have shown that there are simple, separable, and nuclear C*-algebras that can be distinguished by their Cuntz semigroups but not by the Elliott Invariant. So Cuntz semigroup has become popular and important for the research of the classification of C*-algebras. In my talk, I will introduce some basic definitions, examples and related properties.
