An isoperimetric inequality for planar triangulations

Metric Geometry 2016-04-21 v1 Combinatorics

Abstract

We prove a discrete analogue to a classical isoperimetric theorem of Weil for surfaces with non-positive curvature. It is shown that hexagons in the triangular lattice have maximal volume among all sets of a given boundary in any triangulation with minimal degree 6.
