چکیده

We establish some inequalities about the Khovanov-Rozansky cohomologies of braids. These give new upper bounds of the self-linking numbers of transversal knots in standard contact S which is sharper than the well known bound given by the HOMFLY polynomial. We also introduce a sequence of transversal knot invariants, and discuss some of their properties.

Braids, Transversal Links and the Khovanov-rozansky Theory

We establish some inequalities about the Khovanov-Rozansky cohomologies of braids. These give new upper bounds of the self-linking numbers of transversal links in standard contact S which is sharper than the well known bound given by the HOMFLY polynomial. We also introduce a sequence of transversal link invariants, and discuss some of their properties.

Braids and the Khovanov-rozansky Cohomology

In [6], M. Khovanov and L. Rozansky introduced the Z ⊕ Z ⊕ Z-graded KhovanovRozansky cohomology H(B) of a closed braid B. Up to overall shifts of gradings, H(B) is invariant under the Markov moves of the braids and, hence, a link invariant. The graded Euler characteristic of H(B) is a version of the HOMFLY polynomial. In this paper, we use the sign convention given in figure 1, which is opposit...

Khovanov-rozansky Homology of Two-bridge Knots and Links

We compute the reduced version of Khovanov and Rozansky’s sl(N) homology for two-bridge knots and links. The answer is expressed in terms of the HOMFLY polynomial and signature.

Some Differentials on Khovanov-rozansky Homology

We study the relationship between the HOMFLY and sl(N) knot homologies introduced by Khovanov and Rozansky. For each N > 0, we show there is a spectral sequence which starts at the HOMFLY homology and converges to the sl(N) homology. As an application, we determine the KR-homology of knots with 9 crossings or fewer.

On the Quantum Filtration of the Khovanov-rozansky Cohomology

We prove the quantum filtration on the Khovanov-Rozansky link cohomology Hp with a general degree (n + 1) monic potential polynomial p(x) is invariant under Reidemeister moves, and construct a spectral sequence converging to Hp that is invariant under Reidemeister moves, whose E1 term is isomorphic to the Khovanov-Rozansky sl(n)-cohomology Hn. Then we define a generalization of the Rasmussen in...
