Topology Seminar: Recovering HFK^- from sutured Floer homology and contact invariants for open 3-manifolds
by Shea Vela-Vick (Columbia University) in HB 427

I plan to discuss a method for recovering the knot Floer homology "minus" theory of a knot as a directed limit of a collection of sutured Floer homology groups associated to K, together equipped with a naturally defined U-action. Generalizing the techniques used in this construction, one can define invariants of contact structures on open 3-manifolds with F^2 x [0,\infty)-ends and appropriate boundary data at infinity. In this talk, I'll focus on the construction when F is a 2-torus and discuss applications if time permits.Host Department: Rice University-Mathematics
