Title:
Concordance homomorphisms from knot Floer homology

Speaker:
Peter Ozsvath

Abstract:
I will describe an infinite family of homomorphisms from the smooth knot concordance group to Z, defined using a simple modification of knot Floer homology. I will also explain some applications of these homomorphisms. This is joint work with Andras Stipsicz and Zoltan Szabo. (1 hour long talk)
