Topic:String Topology and Closed Geodesics

Date:Monday, April 10
Time/Room:4:00pm - 5:00pm/S-101

Expository talk on work in progress. M.Chas and D.Sullivan introduced a product on the homology of the free loop spaace of a compact, oriented manifold M that has also been studied by R.L.Cohen, V.Godin, J.D.S.Jones, J.Klein, and others. If M is given a metric, the Chas-Sullivan product is closely related to the geometry of closed geodeics on M.
