Topology Date:  Thursday, January 17, 2013 Location:  3866 East Hall (3:00 PM to 4:00 PM) Title:  Symmetries of aspherical manifolds Abstract:   I will describe some results bounding the isometry groups of Riemannian metrics on aspherical manifolds and of the lifted metrics on their universal covers. The general theme is that topological properties of an aspherical manifold often restrict the symmetries of an arbitrary complete Riemannian metric on that manifold. I will illustrate this by explaining why on a finite volume irreducible locally symmetric manifold, no metric has more symmetry than the locally symmetric metric. Possibly, I will also discuss why moduli space is a minimal orbifold. Speaker:  Grigori Avramidi Institution:  University of Chicago Event Organizer:        Edit this event (login required).
