Integer Area Dissections of Lattice Polygons via a Non-Abelian Sperner's Lemma
Published 23 Sep 2024 in math.CO and math.GT | (2409.15178v1)
Abstract: We give a simple and complete description of those convex lattice polygons in the plane that can be dissected into lattice triangles of integer area. A new version of Sperner's Lemma plays a central role.
