An R E-m-coloring of a graph G is a vertex m-coloring of G, which is relaxed (every vertex shares the same color with at most one neighbor) and equitable (the sizes of all color classes differ by at most one). In this article, we prove that every planar graph with minimum degree at least 2 and girth at least 8 has an R E-m-coloring for each integer m≥ 4. We use the discharging method and Hall’s Theorem to simply the structures of counterexamples.
