Title:Security and insecurity in Riemannian manifolds
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Keith Burns (Northwestern)
Abstract:
Two points in a Riemannian manifold form a secure configuration if all geodesics between them can be blocked by a finite number of points; otherwise they are insecure. I will survey the few known results. In particular for compact manifolds with no conjugate points there is an alternative: either the manifold is flat and all configurations are secure or the manifold is not flat and all configurations are insecure.
