Instantons and Bar-Natan homology

Abstract

A spectral sequence is established, whose E2E_{2} page is Bar-Natan's variant of Khovanov homology and which abuts to a deformation of instanton homology for knots and links. This spectral sequence arises as a specialization of a spectral sequence whose E2E_{2} page is a characteristic-2 version of F5F_{5} homology, in Khovanov's classification.
