摘要:

根据树图的结构特点, 应用数学归纳法、组合分析法及组合零点定理, 研究了图G的2-距离和可区别边染色和全染色问题, 得到了树的2-距离和可区别边色数和全色数。

关键词: 树图, 2-距离和可区别边色数, 2-距离和可区别全色数

Abstract:

Based on the structural characteristics of the trees, the 2-distance sum distinguishing edge(total) coloring of trees are studied by using the mathematical induction, combination analytic method and Combinatorial Nullstellensatz, and the 2-distance sum distinguishing edge(total) chromatic numbers are obtained.

Key words: tree, 2-distance sum distinguishing edge chromatic number, 2-distance sum distinguishing total chromatic number
