Event description:
In this talk, we relate topological aspects of a curve on
a surface to its algebraic propertries. In particular, we will give various
estimates of the minimal number of self-intersections of a nontrivial element
of the kth term of the lower central series and derived series of the fundamental
group of a surface. Joint work with Andrew Putman.
