Abstract: Khovanov homology is a categorification of the Jones polynomial and is defined in a purely combinatorial way. The instanton Floer homology for knots, links and three-manifolds is defined more geometrically. In this talk I will show how the instanton Floer homology are related to various versions of Khovanov homologies by spectral sequences. Using these spectral sequences, I will also derive geometrical properties of Khovanov homologies.
