Title:
Geometry of graphs of multicurves

Abstract:
In recent years, a major technique in studying mapping class groups of surfaces is to look at certain graphs associated to the surface which are defined from the combinatorics of curves on the surface. The graphs we study are typically infinite diameter and locally infinite. Instead of the combinatorics of the graph, we are often interested in its large-scale geometry, for example, whether it is Gromov hyperbolic. We will give an introduction to graphs of multicurves and present a result classifying large-scale geometric properties of a family of these graphs in terms of a simple criterion.
