摘要
考虑完全二部图K_(6,n)(6≤n≤38)的点可区别E-全染色.利用组合分析法、反证法及构造染色的方法,给出一类特殊完全二部图的点可区别E-全染色.结果表明:当6≤n≤10时,K_(6,n)的点可区别E-全色数为5;当11≤n≤38时,K_(6,n)的点可区别E-全色数为6.
We considered vertex-distinguishing E-total coloring of complete bipartite graph K6,n(6≤n≤38),and gave the vertex-distinguishing E-total coloring of a class of special complete bipartite graph by using the methods of combinatorial analysis,reduction to absurdity and constructing concrete colorings.The results show that the vertex-distinguishing E-total chromatic number of complete bipartite graph K6,nis 5 when 6≤n≤10 and is 6 when 11≤n≤38.
