Abstract
The Khovanov-Rozansky homologies induce a family of knot concordance invariants (among them the Rasmussen invariant) which give strong lower bounds to the slice genus, and can distinguish between smooth and topological concordance. After some introduction, we will prove linear independence of some of those concordance invariants, using amongst others various spectral sequences that relate the different Khovanov-Rozansky homologies.
