Venue:

University of Aberdeen

Short description of the event:

This operator algebras meeting is one in a series of meetings between Aberdeen and Glasgow; in addition, this one is an "LMS Celebrating New Appointments" meeting, in celebration of the recent appointment of Dr. Aaron Tikuisis as a lecturer in Aberdeen. Participants from other universities are of course welcome to attend, and may contact Aaron Tikuisis for more details. The talks will go from about 12 noon until 5 pm, preceded by tea and coffee, and followed by a dinner. A schedule will be posted very soon.

There will be a fee of £10 per participant.

Speakers

David Evans (Cardiff University) - K-theory and subfactors.

Abstract: I will outline two approaches to conformal quantum field theory via braided subfactors and twisted equivariant K-theory and the connections between these two approaches.

This is joint work with Terry Gannon

Aaron Tikuisis (University of Aberdeen) - Z-stability and the central sequence algebra.

Abstract: Z-stability of a separable C*-algebra can be characterized, in more than one way, by properties of the Cuntz semigroup of the central sequence algebra. In this talk, I will discuss such characterizations and why they hold, and then say more things about the central sequence algebra of nice C*-algebras.

Wilhelm Winter (University of Münster) - Regularity and classification of nuclear C*-algebras.

I will report on recent progress on the interplay between Z-stability and topological dimension for nuclear C*-algebras, and on applications to classification. Among other results, I will explain how locally finite nuclear dimension and Z-stability imply finite nuclear dimension in the simple, unital and monotracial case (joint with Stuart White).

Joachim Zacharias (University of Glasgow) - Nuclear dimension and dynamics.
