摘要: 利用反证法、 组合分析法及构造具体染色的方法, 讨论完全二部图K9,n(9≤n≤92)的点可区别E全染色问题, 给出K9,n(9
≤n≤92) 的最优点可区别E-全染色, 并得到了K9,n(9≤n≤92)的点可区别E-全色数.

关键词: 完全二部图, E全染色, 点可区别E全染色, 点可区别E全色数

Abstract: By using contradiction, the method of combinatorial analysis and the method of constructing specific coloring, we discussed the vertex-distinguishing E-total (VDET) coloring of complete bipartite graph K9,n(9≤n≤92),  gave the optimal VDET coloring of complete bipartite graph K9,n(9≤n≤92), and obtained the VDET chromatic number of K9,n (9≤n≤92).

Key words: complete bipartite graphs, Etotal coloring, vertexdistinguishing E-total coloring, vertexdistinguishing Etotal chromatic number
