The intrinsic geometry of a Jordan domain

Differential Geometry 2007-07-23 v3

Abstract

For a Jordan domain in the plane the length metric space of points connected to an interior point by a curve of finite length is a CAT(0)space and Gromov hyperbolic. With respect to the cone topology, that space plus its boundary at infinity is topologically the same as the original Jordan domain.
