Nonsimple closed geodesics with given intersection number on hyperbolic surfaces

Geometric Topology 2025-08-05 v2

Abstract

We prove that the minimal length of a closed geodesic with self-intersection number kk on any finite-type hyperbolic surface is 2cosh1(1+2k)2\cosh^{-1}(1+2k) for k>1750k>1750. This improves the previously known threshold k>1013350k > 10^{13350}. Our proof is independent of it.
