### Some differentials on Khovanov–Rozansky homology

Jacob Rasmussen

#### Abstract

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.
