Workshop Theme

This workshop is the launching event for the semester-long programme on "Non-Positive Curvature, Group Actions, and Cohomology".
The workshop will focus on the strong connections between fundamental properties of groups acting on non-positively curved spaces and geometric properties of those spaces. The goal is to give an overview of recent developments in the area, encompassing several different notions of nonpositive curvature and their applications within geometric group theory, geometry, and topology.

Deadline for applications: 09 October 2016
