Spring 2001 - Hans Rademacher Lectures in Mathematics

Dusa McDuff

Mathematics Department & Institute for Mathematical Sciences
State University of New York at Stony Brook

will speak on

Geometry and Topology of Groups

Abstract: This series of talks will explore the use of quantum homology and Gromov Witten invariants to investigate groups of symplectomorphisms. I will look both at their homotopy groups and at the geometric properties of the Hofer norm. The first two talks will be suitable for nonexperts, and the others more specialized.
