Special Talk: Rita Gitik (University of Michigan) : "Geodesic triangles in the hyperbolic plane."

Tue, 28/01/202011:00-12:00
Ross 70

Let M be an orientable hyperbolic surface without boundaryand let c be a closed geodesic in M.

We prove that any side of any triangle formed by distinctlifts of c in the hyperbolic plane is shorter than c.

The talk will be presented for advanced undergraduate andbeginning graduate students
