A refinement of Khovanov homology

Published 31 Jul 2019 in math.GT | (1908.00082v1)

Abstract: We refine Khovanov homology in the presence of an involution on the link. This refinement takes the form of a triply-graded theory, arising from a pair of filtrations. We focus primarily on strongly invertible knots and show, for instance, that this refinement is able to detect mutation.
