Short Simple Orthogonal Geodesic Chords on a 2-Disk with Convex Boundary

Differential Geometry 2025-07-11 v1

Abstract

We prove the existence of at least two distinct short, simple orthogonal geodesic chords on a Riemannian 2-disk MM with convex boundary. The lengths of these curves are bounded in terms of the length of M\partial M, the diameter of MM, and the area of MM. We also prove the existence of a short, simple geodesic chord on any Riemannian 2-disk.
