色数

In the third chapter, we shall define the concepts of the adjacent vertex distinguishing incidence coloring and the adjacent vertex distinguishing incidence chromatic number of graphs: For graph G, let Q_u={|u"∈N}U{|u∈N},σ: I→C is a k- incidence coloring of graph G, C_u denotes the set of colors assigned to Q_u.

在第三章中我们将定义图的邻点可区别关联着色及邻点可区别关联色数：对图G，设Q_u={|u"∈N}∪{|u∈N}，σ：I→C为图G的k-关联着色，C_u表示着在Q_u上的色集。

In section three, the conception of the Peterson graph is incited and the fractional chromatic number and the chromatic number of one kind of them are given.

在第三部分中介绍了当k=2时的广义Peterson图的概念，给出了其中一类图的分数色数以及顶点色数。

Before the production, export, as well as affirming cards and membership cards produced by the chromatic number, if there is a spot color.

在制作、输不入后，还必定不否认制卡和会员卡制作的色数，是否有专色。

Prior to the production, export, as well as affirming cards and membership cards produced by the chromatic number, if there is a spot color.

在制作、输不入后，还必定不否认制卡和会员卡制作的色数，是否有专色。

Then we investigate a variation of the edge game chromatic number of a graph called edge game chromatic numberⅡ, and also we give the upbound of edge game chromatic number II of some simple graphs.

我们还提出了第二边对策色数这个概念，在此基础上给出了几类简单图的第二边对策色数的上界。

We shall present some of the basic properties of the vertex and edge chromatic numbers.

我们将介绍顶点色数和边色数的一些基本性质。

In section four, by researching the properties of Kneser graphs, we construct the homomorphism φ between the Kneser graph and the outerplane graph. So the fractional chromatic number and chromatic number are obtained.

在第四部分中通过对Kneser图的一些性质的考察，在Kneser图与外平面图之间建立同态关系，从而得到了外平面图的分数色数与顶点色数。

The paper gives a simulating about a graph with incidence coloring number 6, and obtains the incidence coloring number of the graph.

文中对一个关联色数是6的图进行了仿真，得到了该图的关联色数。

In 2002, Ohba conjectured that every graph G with 2x + 1 or fewer vertices is chromatic choosable.

如果一个图G的选择数等于它的色数，则称该图G是色可选择的。
