Period23 Apr - 29 Apr 2006
The focus of this meeting was the use of topological and geometric methods to study infinite discrete groups. These methods are increasingly being supplemented by powerful new techniques from analysis. Key topics included group actions on CAT(0) and tree-like spaces, filling invariants, cohomology, K-theory and ℓ2 -cohomology, amenability and Kazhdan’s property (T), and deformation spaces, curve complexes and Teichmüller space.
