Tautological classes and symmetry in Khovanov–Rozansky homology

We define a new family of commuting operators Fk in Khovanov–Rozansky link homology, similar to the action of tautological classes in the cohomology of character varieties. We prove that F2 satisfies “hard Lefshetz property” and hence exhibits the symmetry in Khovanov–Rozansky homology conjectured by Dunfield, Gukov, and Rasmussen.

Abstract

We define a new family of commuting operators Fk in Khovanov–Rozansky link homology, similar to the action of tautological classes in the cohomology of character varieties. We prove that F2 satisfies “hard Lefshetz property” and hence exhibits the symmetry in Khovanov–Rozansky homology conjectured by Dunfield, Gukov, and Rasmussen.
