摘要翻译:
连通矩阵的极值特征决定了网络结构对许多网络动力学过程的影响。一个基本的开放问题是大型网络的特征值是否可以用系综平均很好地表示。在此,我们明确地研究了这个问题,并证明了在随机无标度网络中,极端特征值的系综分布随着系统规模的增加收敛到峰值分布,从而验证了系综平均性的概念。我们以同步和流行病传播为例讨论了这一结果的意义。

英文摘要:
The extreme eigenvalues of connectivity matrices govern the influence of the network structure on a number of network dynamical processes. A fundamental open question is whether the eigenvalues of large networks are well represented by ensemble averages. Here we investigate this question explicitly and validate the concept of ensemble averageability in random scale-free networks by showing that the ensemble distributions of extreme eigenvalues converge to peaked distributions as the system size increases. We discuss the significance of this result using synchronization and epidemic spreading as example processes.
