数值研究了当层间耦合受噪声调制时，两层三次映射多重网络的时空行为。我们将这种层间耦合噪声称为复用噪声。根据初始条件，可以在非耦合层中建立各种时空结构。它们可能代表不同形式的嵌合体，空间不规则模式或空间均匀状态。层间耦合强度由具有相同特性的独立高斯色噪声源给出。我们探索的时空动态的相互作用层的复用噪声参数变化时的演变。网络动力学被认为是在相同和不相同的层，不同的层内耦合强度的情况下。结果表明，低频复用噪声在网络中产生孤立态。处于这些孤立态的节点具有特殊的时间动力学，这是第一次揭示。它表明，完全和接近完全同步的层可以实现在某些特性的噪声源。我们分析了如何同步取决于两层的初始制度。图被构造，反映在控制噪声源的频谱和强度的参数的平面中的层同步的程度。
We study numerically the spatio-temporal behavior of a two-layer multiplex network of bistable cubic maps when the interlayer coupling is modulated by noise. We refer to this interlayer coupling noise as a multiplexing noise. Various spatio-temporal structures can be established in the uncoupled layers depending on initial conditions. They may represent chimeras of different forms, spatially irregular patterns or spatially homogeneous states. The interlayer coupling strength between the mirror nodes of the layers is given by independent sources of Gaussian colored noise with identical characteristics. We explore the evolution of the spatio-temporal dynamics of the interacting layers when the multiplexing noise parameters are varied. The network dynamics is considered in the case of identical and nonidentical layers which differ in the intralayer coupling strength. It is shown that the low-frequency multiplexing noise produces the solitary states in the networks. The nodes which are in these solitary states have a special temporal dynamics which is revealed for the first time. It is demonstrated that complete and close to complete synchronization of the layers can be achieved at certain characteristics of the noise sources. We analyze how synchronization depends on the initial regimes of two layers. Diagrams are constructed that reflect the degree of layer synchronization in the plane of parameters that control the spectrum and intensity of noise sources.
