A Categorification of the HOMFLY-PT Polynomial with a Spectral Sequence to Knot Floer Homology

Abstract

Let $E_k^F(D)$ be the spectral sequence induced by the oriented cube of resolutions on knot Floer homology. We prove that $E_2^F(D)$ is a triply graded link invariant whose graded Euler characteristic is the HOMFLY-PT polynomial and that the higher pages are link invariants. By construction, the spectral sequence converges to knot Floer homology. We show that the rank of the torsion-free part of $E_2^F(D)$ is the rank of HOMFLY-PT homology.
