近年来，Estrada指数的对数被提出作为一种谱测度来有效地刻画复杂网络的鲁棒性。在本文中，我们探讨了加权网络中的Estrada指标，并发展了各种扰动结果的基础上谱图理论。它表明，网络的鲁棒性可以增强，即使当一些边的权重减少。这对网络设计和优化具有特殊的理论和实际意义。
The logarithm of the Estrada index has been proposed recently as a spectral measure to character efficiently the robustness of complex networks. In this paper, we explore the Estrada index in weighted networks and develop various perturbation results based on spectral graph theory. It is shown that the robustness of a network may be enhanced even when some edge weights are reduced. This is of particular theoretical and practical significance to network design and optimization.
