摘要: 令
G是一个顶点数为
n的简单图,满足
n≥4
k,
k是任意正整数。假设
,则图
G可划分成
k-1个点不交的4-团和一个弦圈,使得弦圈上点的度大于等于3或4。
Abstract:
Let
G be a graph of order
n with
n≥4k, where
k is a positive integer. Suppose that
, then the partition of
G can be
k-1 vertex disjoint 4-cliques and a chordal cycle, where the degree of vertexes in this chordal cycle is equal or greater than 3 or 4.
