Khovanov homology of tangles
Wojciech Politarczyk
08.11.2016
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.
