On some $p$-differential graded link homologies

Abstract

We show that the triply graded Khovanov-Rozansky homology of knots and links over a field of positive odd characteristic pp descends to an invariant in the homotopy category finite-dimensional pp-complexes. A pp-extended differential on the triply graded homology discovered by Cautis is compatible with the pp-DG structure. As a consequence we get a categorification of the Jones polynomial evaluated at an odd prime root of unity
