Abstract

Odd Khovanov Homology is a homological invariant of knots and links that permits a Bar-Natan category presentation. In this dissertation, we extend the odd Khovanov bracket to link cobordisms and prove that our construction is functorial up to sign. We then build an odd Khovanov theory for dotted link cobordisms. Out of the dotted theory, a module structure on the odd Khovanov homology of a diagram over the exterior algebra of the diagram’s coloring group arises. We finish by using our functoriality result to prove that if n is even or if the knot has even framing, then the odd Khovanov homology of the n-cable of a knot admits an action of the Hecke algebra H(q2, n) at q = i.
