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.

Khovanov同调的一个改进

我们改进了在连杆上存在对合的Khovanov同调。这种细化采用三次分级理论的形式，由一对过滤产生。我们主要关注强可逆结点，并表明，例如，这种改进能够检测突变。
