Let $|G|$ denote the number of vertices of $G$ and $\\Delta=\\Delta(G)$ the maximum degree of a vertex in $G$. We prove that a graph $G$ of order at least 6 is equitably $\\Delta$-colorable if $G$ satisfies $(|G|+1)/3 \\leq \\Delta < |G|/2$ and none of its components is a $K_{\\Delta +1}$.", "revisions": [ { "version": "v1", "updated": "2014-08-26T08:21:58.000Z" } ], "analyses": { "subjects": [ "05C15" ], "keywords": [ "intermediate maximum degree", "equitable coloring", "color classes differ", "adjacent vertices receive" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1408.6046C" } } }
