Does Khovanov homology detect the unknot?

Geometric Topology 2008-05-30 v1 Quantum Algebra

Abstract

We determine a wide class of knots, which includes unknotting number one knots, within which Khovanov homology detects the unknot. A corollary is that the Khovanov homology of many satellite knots, including the Whitehead double, detects the unknot.
