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.
In the second talk, I'll discuss how Khovanov homology and its generalizations lead to a relation between the HOMFLY polynomial and the topology of flag varieties.
