Topology Seminar: Concordance and the knot Floer complex
by Jennifer Hom (University of Pennsylvania) in HB 427
We will use the knot Floer complex, in particular the invariant epsilon, to define a new smooth concordance homomorphism. Applications include a formula for tau of iterated cables, better bounds (in many cases) on the 4-ball genus than tau alone, and a new infinite family of smoothly independent topologically slice knots. We will also discuss various algebraic properties of this new homomorphism. Host Department: Rice University-Mathematics
