Title:  Non-orientable surfaces and mapping class group orbit closures

Abstract:   The space of measured laminations on a surface-which can be viewed as the closure of the set of weighted simple closed curves-is a fundamental tool when studying hyperbolic surfaces. When the surface is orientable, this space and the action of the mapping class group on it is by now well-understood. However, the situation is very different in the non-orientable case and I will talk about some recent results in this direction. In particular we will describe the orbit closures of the mapping class group action on the space of measured laminations, which in the orientable setting is a result of Lindenstrauss-Mirzakhani. This is joint work with Gendulphe, Pasquinelli, and Souto.

This talk will start at 4:10pm.
