On the chromatic number of 2-dimensional spheres

Combinatorics 2022-10-04 v2

Abstract

In 1976 Simmons conjectured that every coloring of a 2-dimensional sphere of radius strictly greater than 1/21/2 in three colors has a couple of monochromatic points at the distance 1 apart. We prove this conjecture.
