The Khovanov-Rozansky concordance invariants

The Khovanov-Rozansky homologies induce a family of knot concordance invariants
that give strong lower bounds to the slice genus,
and wedge themselves between the smooth and the topological category.
First of these Khovanov-Rozansky concordance invariants is the Rasmussen invariant,
but we will see many others, which can be distinguished using spectral sequences.
Geometrical applications will be discussed.
