Khovanov-Rozansky cycle calculus for bipartite links
Abstract
Bipartite calculus is a direct generalization of Kauffman planar expansion from to arbitrary , applicable to the restricted class of knots which are entirely made of antiparallel lock tangles. Whenever applicable, it allows a straightforward generalization of the Khovanov calculus without a need of the technically complicated matrix factorization used for arbitrary in the Khovanov-Rozansky (KR) approach. The main object here is the -dimensional hypercube with being the number of bipartite vertices. Maps, differentials, complex and Poincar\'e polynomials are straightforward and indeed reproduce the Khovanov-Rozansky polynomials in the known cases. This provides a great simplification of the Khovanov-Rozansky calculus on the bipartite locus, what can make it an accessible tool for the study of superpolynomials.
