Near ideal decompositions of ideal polygons

Geometric Topology 2026-01-09 v2

Abstract

This article gives a short proof that all ideal polygons admit a short orthogeodesic decomposition. Specifically, all nn-gons admit an orthogeodesic decomposition with orthogeodesics all of length at most 2log(n)\sim 2 \log(n), and this is roughly optimal.
