Diffusion Dynamics and Optimal Coupling in Directed Multiplex Networks

Alejandro Tejedor, Anthony Longjas, Efi Foufoula-Georgiou, Tryphon Georgiou, Yamir Moreno

摘要:

我们研究了作用于有向多重网络的扩散过程的动力学,即,耦合多层网络,其中至少一层由有向图组成。我们发现,定向多路复用网络可能会表现出更快的扩散在一个中间程度的耦合比当两个层完全耦合。我们使用三个简单的多路复用的例子和现实世界的拓扑结构来说明的有向动力学的特点,产生一个政权,其中存在一个最佳的耦合。鉴于有向网络和多层网络在自然界中的普遍存在,我们的研究结果可能对多级复杂系统的动力学走向最优性具有重要意义。

英文摘要:

We study the dynamics of diffusion processes acting on directed multiplex networks, i.e., coupled multilayer networks where at least one layer consists of a directed graph. We reveal that directed multiplex networks may exhibit a faster diffusion at an intermediate degree of coupling than when the two layers are fully coupled. We use three simple multiplex examples and a real-world topology to illustrate the characteristics of the directed dynamics that give rise to a regime in which an optimal coupling exists. Given the ubiquity of both directed and multilayer networks in nature, our results could have important implications for the dynamics of multilevel complex systems towards optimality.
