摘要
进一步研究了平方图的邻点全和可区别非正常全染色问题:利用平方图的结构构造了路、圈、毛毛虫、广义星以及最大度为3且不含2度点的树的平方图,通过组合分析法得到上述5类平方图的邻点全和可区别非正常全色数。
To further study the problem of the neighbor full sum distinguishing non-proper total coloring of the square graphs,the structural of square graphs are used for constructing paths,cycles,caterpillars,generalized stars and trees with maximum degree 3 and having no vertex of degree 2.And the neighbor full sum distinguishing total chromatic improper number of the above five types of square graphs are determined with the combinatorial analysis.
