pdf * Quantum Topology / Hopf Algebra Seminar
Khovanov Homology and Lee Homology
Louis Kauffman (UIC)
3:00 PM in SEO 612
Lee homology is a variant of Khovanov homology, using a different Frobenius algebra. We will review how this structure comes about and show how to calculate Lee homology. We then explain how Lee homology and Khovanov homology combine to give information about the 4-ball genus of some knots (Rasmussen invariant).
