Abstract: Nuclear C*-algebras (or equivalently amenable C*-algebras) are a large class of C*-algebras amenable to study due to their finite-dimensional approximation property. Z-stable C*-algebras are C*-algebras that satisfy a regularity property which proves fundamental for the known classification results that we know so far. In this talk, I will describe the Cuntz semigroup and its properties. Evidence that the Cuntz semigroup can be used as an invariant to classify amenable C*-algebras will be discussed.

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. To join us click sju.webex.com/meet/nikolaei (5 min in advance) and igor DOT v DOT nikolaev AT gmail DOT com to subscribe/unsubscribe for the mailing list, to propose a talk or to suggest a speaker. Pending speaker's consent, we record and publish all talks at the hyperlink "video" on speaker's profile at the "Past talks" section. The slides can be posted by providing the organizers with a link in the format "myschool.edu/~myfolder/myslides.pdf". The duration of talks is 1 hour plus or minus 10 minutes.
