Khovanov's Categorification of the Jones Polynomial

** 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.

My talk will be similar to a talk I gave at the Topology and Geometry
seminar last November (see
here
); it will be based on the same
paper and will mostly follow the same
handout. The only new material will be
on the back side of the handout, which will be printed with a list of
reasons for
why categorification is interesting.
