## Seminar on Tuesday, April 3: Scott Wolpert

This Tuesday at 4:30, the seminar hosts Scott Wolpert of the University of Maryland.

Title: Weil-Petersson Riemannian and symplectic geometry: geodesic-lengths, Fenchel-Nielsen twists and Thurston shears

Abstract: We discuss the correspondence between Weil-Petersson geometry on Teichmuller space $T$ and the hyperbolic geometry of surfaces, the unions of thrice punctured spheres. A theme is that the mapping class group is the symmetry group of geometries of $T$.
