چکیده
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, Transversal Knots and the Khovanov-rozansky Theory
We establish some inequalities about the Khovanov-Rozansky cohomologies of braids.

متن کاملOn 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...
متن کاملBraids 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...
متن کاملLink Homology Theories from Symplectic Geometry
For each positive integer n, Khovanov and Rozansky constructed an invariant of links in the form of a doubly-graded cohomology theory whose Euler characteristic is the sl(n) link polynomial. We use Lagrangian Floer cohomology on some suitable affine varieties to build a similar series of link invariants, and we conjecture them to be equal to those of Khovanov and Rozansky after a collapse of th...
متن کاملKhovanov-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.
