Finitely dependent random colorings of bounded degree graphs

Abstract

We prove that every (possibly infinite) graph of degree at most dd has a 4-dependent random proper 4d(d+1)/24^{d(d+1)/2}-coloring, and one can construct it as a finitary factor of iid. For unimodular transitive (or unimodular random) graphs we construct an automorphism-invariant (respectively, unimodular) 2-dependent coloring by 3d(d+1)/23^{d(d+1)/2} colors. In particular, there exist random proper colorings for Zd\Z^d and for the regular tree that are 2-dependent and automorphism-invariant, or 4-dependent and finitary factor of iid.
