随机图的匹配能量

The matching energy of random graphs

Xiaolin Chen, Xueliang Li, Huishu Lian

摘要:

图的匹配能量是由Gutman和Wagner提出的,定义为图的匹配多项式的根的绝对值之和。对于具有固定概率$p\in (0,1)$的$n$阶随机图$G_{n,p}$,Gutman和Wagner [I. Gutman,S. Wagner,The matching energy of a graph,Discrete Appl.Math.160(2012),2177- 2187]提出了$G_{n,p}$的匹配能量几乎必然收敛于$\frac{8\sqrt{p}}{3π}n^{\frac{3}{2}}$的猜想。本文用分析的方法证明了这个猜想是成立的。

英文摘要:

The matching energy of a graph was introduced by Gutman and Wagner, which is defined as the sum of the absolute values of the roots of the matching polynomial of the graph. For the random graph $G_{n,p}$ of order $n$ with fixed probability $p\in (0,1)$, Gutman and Wagner [I. Gutman, S. Wagner, The matching energy of a graph, Discrete Appl. Math. 160(2012), 2177--2187] proposed a conjecture that the matching energy of $G_{n,p}$ converges to $\frac{8\sqrt{p}}{3π}n^{\frac{3}{2}}$ almost surely. In this paper, using analysis method, we prove that the conjecture is true.
