Rasmussen s-invariants of satellites do not detect slice knots

arXiv:1512.08931

Abstract

We present a large family of knots for which the Rasmussen s-invariants of arbitrary satellites do not detect sliceness. This answers a question of Hedden. The proof hinges on work of Kronheimer-Mrowka and Cochran-Harvey-Horn.
