Abstrakt: Khovanov homology is a certain invariant of links that
categorifies the Jones polynomial, i.e. the Jones polynomial can be recovered from Khovanov homology as a graded Euler characteristic. Jones polynomial can be extended to an invariant of tangles. We will sketch the construction of this extension of the Jones polynomial and show how to categorify this invariant.
