We study the space of slice torus invariants. In particular we characterise the set of values that slice torus invariants may take on a given knot in terms of the stable smooth slice genus. Our study reveals that the resolution of the local Thom conj... Read More about On the values taken by slice torus invariants.

Rasmussen's spectral sequences and the sl_N-concordance invariants (2014)

Combining known spectral sequences with a new spectral sequence relating reduced and unreduced slN-homology yields a relationship between the Homflypt-homology of a knot and its slN-concordance invariants. As an application, some of the slN-concordan... Read More about Rasmussen's spectral sequences and the sl_N-concordance invariants.
