摘    要:设G是一个简单图,i是一个正整数,X是V(G)的一个子集,如果X中任意两个点的距离都大于i,则称X是一个i-宽度箱,i叫做X的宽度,一个图G的泛宽度色数xp(G)是使得G的顶点集V(G)被剖分成宽度两两不同的k个宽度箱的最小整数k,本文给出了轮,扇及图Kn的推广的hajos sum的泛宽度色数,

关 键 词:泛宽度染色  i-宽度箱  hjos  SUM  宽度色数

Abstract:Let G = (V(G), E(G)) be a simple graph, i be a positive integer. Then X lohtain in V(G) is a i- packing if the distances of any pairwise vertices of X are greater than i. The packing chromatic number xp (G) of a graph G is the smallest integer k, which make the vertex set of G can be partitioned into k different packings. This paper presents the packing chromatic numbers of some special graphs.
Keywords:sum
