A geometric spectral sequence in Khovanov homology


Zoltán Szabó

Princeton University



In this talk we will discuss a link invariant that is closely related to both Khovanov homology and Heegaard Floer homology. The construction was inspired by a similar spectral sequence from the reduced mod 2 Khovanov homology of a link to the Heegaard Floer homology of the double branched cover of the link.
