1) equitable L (2,1)-labeling
均匀L ( 2,1)-标号
2) L(2,1)-labeling
L(2,1)-标号
1.
In this thesis, we firstly summarize the main results and evolution on the L(2,1)-labeling in recent years, then we investigate some graphs:(1) We explore the L(2,1)-labeling of cacti, and prove thatλ(G)≤△(G)+2 when△(G)≥5.
图的L(2,1)-标号来源于Hale所介绍的频率分配问题。
4) L ( 2,1)-labeling
L ( 2,1)-标号
1.
For example, vertex coloring, acyclic coloring, 2-distance coloring, star coloring, and L ( 2,1)-labeling and so on, so that some of the study methods of them can be used in{ }P_r -free coloring, and provide some theory knowledge for further study.
具体研究内容如下:首先,综述了一般图的着色的概念和研究现状,例如:顶点着色、无圈着色、2-距离着色、星着色以及L ( 2,1)-标号等,对于这些着色与标号的研究方法可直接应用于图的{ }P_r -自由着色,从而为后文的研究做一些铺垫。
5) L(2,1)-labelling
L(2,1)-标号
1.
L(2,1)-labelling number of 2-outer planar graphs
2-外平面图的L(2,1)-标号数
6) L(2,1)-edge-labeling
L(2,1)-边-标号
1.
We usually denoted byλ\'(G) the L(2,1)-edge-labeling number.
图G的线图L(G)的L(2,1)-标号实际上等价于图G的L(2,1)-边-标号。
