For a given graphG, the clique numberω(G), the chromatic numberχ(G) and the maximum degree Δ(G) satisfyω(G) ≤χ(G) ≤ Δ(G)+1. Brooks showed that complete graphs and odd cycles are the only graphs attaining the upper bound Δ(G)+1. Reed conjectured. In this paper we will present some partial solutions for this conjecture.
