The Khovanov-Rozansky concordance invariants
by
Lukas Lewark
Durham University, UK
Coauthors: Andrew Lobb

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.
