Title: Random Measured Laminations and Teichmüller Space
Speaker: Tina Torkaman, University of Chicago
Abstract:
In this talk, we introduce a canonical geodesic current $KX$ for each $X ∈ T_g$, representing a randomly chosen simple closed geodesic on $X$. We establish results analogous to Bonahon's work on the Liouville measure. In particular, we show that the map $X → KX$ defines a proper embedding of Teichmüller space $T_g$ into the space of geodesic currents. This embedding leads to a compactification of $T_g$ that differs from Thurston's compactification, which Bonahon's results yield via the Liouville measure. We will discuss the construction of $KX$ and its geometric properties. This is joint work with Curt McMullen.
