查询词典 chromatic number

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。

If for any uv∈E, C_u≠C_v, then we callσis a k-adjacent vertex distinguishing incidence coloring of G andχ_=min{k| there exists a k- adjacent vertex distinguishing incidence coloring of G} is the adjacent vertex distinguishing incidence chromatic number of G.

若对任意uv∈E满足C_u≠C_v，则称σ为G的k-邻点可区别关联着色，并称X_=min{k|存在G的k-邻点可区别关联着色}为G的邻点可区别关联色数。
