Randomly coloring simple hypergraphs with fewer colors

Abstract

We study the problem of constructing a (near) uniform random proper qq-coloring of a simple kk-uniform hypergraph with nn vertices and maximum degree Δ\Delta. (Proper in that no edge is mono-colored and simple in that two edges have maximum intersection of size one). We show that if qmax{Cklogn,500k3Δ1/(k1)}q\geq \max\{C_k\log n,500k^3\Delta^{1/(k-1)}\} then the Glauber Dynamics will become close to uniform in O(nlogn)O(n\log n) time, given a random (improper) start. This improves on the results in Frieze and Melsted [5].
