Jason Behrstock: Temple geometry seminar (5 pm,Tuesday, Jan 22)
Jason Behrstock of CUNY will be speaking in the Temple Geometry and Topology Seminar. Title: Divergence, thick groups, and morse geodesics Abstract: In a metric space the divergence of a pair of rays is a way to measure how quickly … Continue reading
PATCH seminar at UPenn
Speakers will be John Pardon and Larry Guth. Abstracts: John Pardon (3:30): Totally disconnected groups (not) acting on three-manifolds. Hilbert´s Fifth Problem asks whether every topological group which is a manifold is in fact a (smooth!) Lie group; this was … Continue reading

Joseph Maher’s talk at the Geometry/Topology seminar (4 pm Tuesday, November 20)
Joseph Maher will be speaking in the Temple Geometry and Topology Seminar. Title: Statistics for Teichmuller geodesics. Abstract: We describe two ways of picking a geodesic “at random” in a space, one coming from the standard Lebesgue measure on the … Continue reading

Patricia Cahn’s talk at the Geometry/Topology seminar (October 9th, 4pm)
Title: Algebras counting intersections and self-intersections of curves Abstract: Goldman and Turaev discovered a Lie bialgebra structure on the vector space generated by free homotopy classes of loops on an oriented surface. Goldman’s Lie bracket gives a lower bound on … Continue reading
