Wall-crossing Morphisms in Khovanov-rozansky Homology
نویسنده
چکیده
We define a wall-crossing morphism for KhovanovRozansky homology; that is, a map between the KR homology of knots related by a crossing change. Using this map, we extend KR homology to an invariant of singular knots categorifying the Vasilliev derivative of the HOMFLY polynomial, and of sln quantum invariants.

A computation in Khovanov-Rozansky Homology
We investigate the Khovanov-Rozansky invariant of a certain tangle and its compositions. Surprisingly the complexes we encounter reduce to ones that are very simple. Furthermore, we discuss a “local” algorithm for computing Khovanov-Rozansky homology and compare our results with those for the “foam” version of sl3-homology.
متن کاملSome 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.
متن کاملKhovanov-Rozansky Homology and Topological Strings
We conjecture a relation between the sl(N) knot homology, recently introduced by Khovanov and Rozansky, and the spectrum of BPS states captured by open topological strings. This conjecture leads to new regularities among the sl(N) knot homology groups and suggests that they can be interpreted directly in topological string theory. We use this approach in various examples to predict the sl(N) kn...
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.
متن کاملProperties of Khovanov homology for positive braid knots
In this paper we solve one open problem from [13] and give some generalizations. Namely, we prove that the first homology group of positive braid knot is trivial. Also, we show that the same is true for the Khovanov-Rozansky homology [15] (sl(n) link homology) for any positive integer n.
