摘要: 图的染色问题是图论中的一个重要研究方向,在计算机科学,组合优化和网络优化等方面有非常重要的应用,全然色是一种重要的染色。本文利用权值转移的方法证明了,如果G是最大度大于等于八的可嵌入到欧拉示性数非负曲面的图,且G中不包含相邻的4-圈,那么图G的全色数等于最大度加一。
Abstract: Graph coloring is an important research direction in graph theory. It has very important applica-tions in computer science, combination optimization and network optimization. Total coloring is an important type of coloring. In this paper, we use the discharging method to prove that if G is a graph of maximum degree that is equal or greater than eight, and it can be embedded into a nonnegative surface of Euler characteristic, and G does not contain adjacent 4-cycles, then the total chromatic number of G is equal to its maximum degree plus one.
