Concordance invariants from truncated Heegaard Floer homology

Linh Truong (Columbia University)

Many concordance invariants have been constructed from Heegaard Floer homology. I will describe a sequence of concordance invariants \nu_n constructed from truncated Heegaard Floer homology that generalize the Ozsvath-Szabo \nu invariant and the Hom-Wu \nu^+ invariant.
