摘要: 利用反证法、 构造染色法和色集合事先分配法, 讨论完全四部图Kn1,n2,n3,n4n1≤n2=n3<n4或n1=n2=n3=n4)的顶点被多重集可区别的一般全染色, 给出一个最优染色方案, 并确定相应染色的色数.

关键词: 完全四部图, 一般全染色, 多重集, 色集合, 可区别

Abstract: By using the method of contradiction,  the method of constructing concrete coloring and distributing the color sets in advance, we discussed the general total colorings of complete 4-partite graph Kn1,n2,n3,n4n1≤n2=n3<nor n1=n2=n3=n4) that were vertex-distinguished by multisets. We gave an  optimal coloring scheme and determined the chromatic numbers of the corresponding colorings.

Key words: complete 4-partite graph, general total coloring, multiset, color set, distinguishing
