图G的(k
r)-着色是图G的一个正常k-着色
并满足G中的每一个顶点的邻点的颜色数至少为这个顶点的度d(v)和r的最小值.使得图G有(k
r)-着色的最小整数k称为图G的r-多彩色数
用χr(G)表示.研究了路的平方图和路的直积图的r-多彩着色
得到了r-多彩着色数.
A(k
r)-coloring of G is a proper coloring with k colors such that for every vertex v with degree d(v) in G
the color number of the neighbors of v is at least min{d(v)
r}. The smallest integer k such that G has an(k
r)-coloring is called the r-hued chromatic number and denoted by χr(G). In this paper
we study the r-hued coloring of direct product of path with the square of path
and obtain its r-hued chromatic number.
