Geometry Topology Working Seminar
Friday, February 25, 2011 - 2:00pm
1.5 hours (actually 80 minutes)
I'll present a new, simple proof that the Torelli group is generated by (infinitely many) bounding pair maps. At the end, I'll explain an application of this approach to the hyperelliptic Torelli group. The key is to take advantage of the "complex of minimizing cycles."
