Closed geodesics on hyperbolic surfaces with few intersections

Geometric Topology 2025-10-02 v2

Abstract

We prove that, if a closed geodesic Γ\Gamma on a complete finite type hyperbolic surface has at least 2 self-intersections, then the length of Γ\Gamma has an lower bound 2log(5+26)2\log(5+2\sqrt6), and the lower bound is sharp, attained on a corkscrew geodesic on a thrice punctured sphere.
