Integrated Neighborhood Colorings of Graphs

Combinatorics 2022-01-11 v3

Abstract

The idea that those different from you are "unfriendly" is captured in the definition of unfriendly 2-colorings in graph theory in a paper by Aharoni, Milner and Prikry, where they prove that every finite graph has an unfriendly coloring. We give a more general definition for all n>1, that we call "integrated" rather than "unfriendly." Then we prove that every finite graph has an integrated n-coloring, n>1. We then give some applications to various graph coloring problems and to some max-cut problems.
