Every graph is a cut locus

Differential Geometry 2016-08-14 v4

Abstract

We prove that every connected graph can be realized as the cut locus of some point on some Riemannian surface SS which, in some cases, has constant curvature. We study the stability of such realizations, and their generic behavior.
