Group actions on compact spaces (Colloquium)

Group actions on compact spaces (Colloquium)

Prof. Dr. Arthur Bartels

Actions of discrete groups on compact spaces have been important for recent progress on the Borel conjecture. In this talk I will review Borel's conjecture on the topological rigidity of aspherical manifolds and discuss the role of actions on compact spaces. This leads to a regularity condition for such actions that strengthens amenability.
