Buildings and C*-algebras

Presented by: 
Alina Vdovina Newcastle University
Date: 
Thursday 26th January 2017 - 11:30 to 12:30
Venue: 
INI Seminar Room 1
Abstract: 

We will give an elementary introduction to the theory of buildingsfrom a geometric point of view. Namely, we present buildings as universal coversof finite polyhedral complexes. It turns out that the combinatorial structure of these complexesgives rise to a large class of higher rank Cuntz-Krieger algebras, which K-theory can be explicitly computed.
