Roever Colloquium: A tale on geometric structures
Speaker: Ursula Hamenstädt, University of Bonn
Abstract: A Riemannian metric on a closed manifold M can be thought of as providing M with a notion of length and size. An old but vague question is the following: is there a best ge metric structure which allows to recover topological features of a manifold? I'll discuss what an Einstein metric is and why sometimes such a metric serves this purpose. I then discuss some new families of examples and how they fit into a largely speculative broader picture. Mostly based on joint work with Frieder Jaeckel and Henri Guenancia.
Host: Charles Ouyang
Reception to follow at Cupples I, Room 200 (Lounge) from 2:00pm to 3:00pm
