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.本文得到如下结果:设A(?)E(Kn,r),|A|≤1,且n≤r≤min{n+6,2n-3),则G=Kn,r-A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 A (?) E(Kn,r), |A| ≤ 1, and n ≤ r min{n + 6,2n - 3}, then Kn,r - A is determined by its cycle length distribution.
