由圈长分布确定的偶图
Bipartite Graphs Determined by Their Cycle Length Distributions
【摘要】 阶为n的图G的圈长分布是序列(c1,c2,…,cn),其中ci是图G中长为i的圈数.作者得到如下结果:设n≤r≤min{n+6,2n-3},则Kn,r是由它的圈长分布确定的.
【Abstract】 The cycle length distribution of a graph of order n is (c1, c2 ,…, cn ), where ci is the number of cycles of length i. In this paper,we obtain the following result: Let n≤r≤ min {n+6,2n-3}, then Kn,r is determined by its cycle length distribution.
