Certain Hyperbolic Regular Polygonal Tiles are Isoperimetric

Metric Geometry 2022-02-08 v2

Abstract

The hexagon is the least-perimeter tile in the Euclidean plane. On hyperbolic surfaces, the isoperimetric problem differs for every given area. Cox conjectured that a regular kk-gonal tile with 120-degree angles is isoperimetric for its area. We prove his conjecture and more.
