Geometric Topology Seminar

Speaker: Jason Behrstock

Title: Higher dimensional filling and divergence for mapping class groups.

Abstract: We will discuss filling and divergence functions. We will describe their behaviors for mapping class groups of surfaces and show that these functions exhibit phase transitions at the rank, in analogy to the corresponding result for symmetric spaces. This work is joint with Cornelia Drutu.
