Abstract: The Cuntz semigroup is a geometric refinement of K-theory that was introduced by Cuntz in the 1970s in his pioneering work on the structure of simple C*-algebras. This powerful invariant has seen many applications in the structure and classification theory of C*-algebras. Recently, it has also become clear that Cuntz semigroups are interesting objects of study in their own right.

In these lectures, I will give a short introduction to Cuntz semigroups, and present some examples and applications.

Noncommutative geometry in NYC

Series comments: Noncommutative Geometry studies an interplay between spatial forms and algebras with non-commutative multiplication. Our seminar welcomes talks in Number Theory, Geometric Topology and Representation Theory linked to the context of Operator Algebras. All talks are kept at the entry-level accessible to the graduate students and non-experts in the field.
