We study transverse representatives of an oriented topological knot type K in the tight contact 3-sphere, where the classical invariant of transverse isotopy introduced by Bennequin is the self-linking number.

I will describe a spectral sequence that starts at reduced odd Khovanov homology and converges to a version of instanton homology for double branched covers.
This is a joint Topology - Algebraic Topology seminar.
