Khovanov's Categorification of the Jones Polynomial
Dror Bar-Natan (Toronto)
Abstract:
After quickly recalling what is the Euler characteristic and
what is homology and after briefly describing the Jones polynomial, I will
move on to describe in simple terms Khovanov's novel "Categorification of
the Jones Polynomial", which is to the Jones polynomial as homology is to
the Euler characteristic. Namely, it is much more interesting.
