A refinement of Khovanov homology

Andrew Lobb, Liam Watson

Published 2019-07-31Version 1

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.
