Flag varieties and the HOMFLY polynomial I
Jacob Rasmussen
(Cambridge)
Abstract
Khovanov homology is an invariant of knots in $S^3$. In its original form,
it is a "homological version of the Jones polynomial"; Khovanov and
Rozansky have generalized it to other knot polynomials, including the
HOMFLY polynomial.
The first talk will be an introduction to Khovanov homology and its generalizations.
