复用网络中的层内同步

Intra-layer synchronization in multiplex networks

Lucia Valentina Gambuzza, Mattia Frasca, Jesus Gomez-Gardeñes

摘要:

研究了通过非均匀介质间接耦合的$N$振子的同步问题。该系统是正式的多层网络,其中的顶层是由断开的振荡器和底部的,建模的介质,根据给定的拓扑结构耦合的振荡器组成。介质和顶层的不同动态通过包括它们之间的频率失配来解释。我们展示了一种新的同步机制,因为层内相干性不一定需要层间相干性。这种制度出现在温和的条件下的底层:任意拓扑结构可以被认为是,只要他们支持同步的振荡器的介质。密度依赖阈值的存在,在群体感应现象也被证明。

英文摘要:

We study synchronization of $N$ oscillators indirectly coupled through a medium which is inhomogeneous and has its own dynamics. The system is formalized in terms of a multilayer network, where the top layer is made of disconnected oscillators and the bottom one, modeling the medium, consists of oscillators coupled according to a given topology. The different dynamics of the medium and the top layer is accounted by including a frequency mismatch between them. We show a novel regime of synchronization as intra-layer coherence does not necessarily require inter-layer coherence. This regime appears under mild conditions on the bottom layer: arbitrary topologies may be considered, provided that they support synchronization of the oscillators of the medium. The existence of a density-dependent threshold as in quorum-sensing phenomena is also demonstrated.
