摘要:

流行病学、社会科学、电力运输、经济学和工程学中的真实世界系统通常被描述为多层网络。在这里,我们首先定义和计算多层网络的对称性,然后研究在这些网络中的集群同步的出现。我们区分独立层对称性,发生在一个层,是独立的其他层和依赖层对称性,涉及节点在不同的层。我们研究了集群同步解的稳定性,通过将问题解耦成多个独立的块,并通过主稳定性函数评估每个块的稳定性。我们看到,与依赖层对称性相关的块具有与其他块不同的结构,这影响了与这些对称性相关的簇的稳定性。最后,我们在一个完全模拟的实验中验证了理论,其中七个电子振荡器的三种类型的连接与两种耦合。

英文摘要:

Real-world systems in epidemiology, social sciences, power transportation, economics and engineering are often described as multilayer networks. Here we first define and compute the symmetries of multilayer networks, and then study the emergence of cluster synchronization in these networks. We distinguish between independent layer symmetries which occur in one layer and are independent of the other layers and dependent layer symmetries which involve nodes in different layers. We study stability of the cluster synchronous solution by decoupling the problem into a number of independent blocks and assessing stability of each block through a Master Stability Function. We see that blocks associated with dependent layer symmetries have a different structure than the other blocks, which affects the stability of clusters associated with these symmetries. Finally, we validate the theory in a fully analog experiment in which seven electronic oscillators of three kinds are connected with two kinds of coupling.
