层退化触发复用网络中的突然结构转变

Layer degradation triggers an abrupt structural transition in multiplex networks

Emanuele Cozzo, Guilherme Ferraz de Arruda, Francisco A. Rodrigues, Yamir Moreno

摘要:

网络鲁棒性是网络科学的一个核心问题,无论是从理论还是实践的角度来看。在本文中,我们表明,层退化,被理解为连续或离散损失的链接的重量,触发结构转变所揭示的突然变化的代数连接图。与传统的单层网络不同,多路复用网络存在两个阶段,一个阶段是保护系统免受其某些层中的链路故障的影响,另一个阶段是所有系统都感测到在一个单层中发生的故障。我们还给出了准确的临界值的层内链接的重量发生连续层退化和它的关系的值之间的耦合层。这种关系使我们能够揭示层退化下观察到的过渡和层间耦合的变化下观察到的过渡之间的连接。

英文摘要:

Network robustness is a central point in network science, both from a theoretical and a practical point of view. In this paper, we show that layer degradation, understood as the continuous or discrete loss of links' weight, triggers a structural transition revealed by an abrupt change in the algebraic connectivity of the graph. Unlike traditional single layer networks, multiplex networks exist in two phases, one in which the system is protected from link failures in some of its layers and one in which all the system senses the failure happening in one single layer. We also give the exact critical value of the weight of the intra-layer links at which the transition occurs for continuous layer degradation and its relation to the value of the coupling between layers. This relation allows us to reveal the connection between the transition observed under layer degradation and the one observed under the variation of the coupling between layers.
