摘要:

同步是由相互作用振荡单元组成的各类系统中的重要现象,这些系统既包括自然系统(如神经元、生化反应、心肌细胞),也包括人工系统(如节拍器、电网、Josephson 结)。Kuramoto 模型为这些系统提供了简单描述,并在其数学探索中发挥了作用。本文研究该模型,同时结合在许多系统中观察到的两个常见特征:外部周期驱动和单元之间的高阶相互作用。我们表明,这些因素的结合导致非常丰富的分岔情形,产生系统的 11 种不同渐近状态,并在受迫同步与自发同步之间形成竞争。我们特别发现,在无驱动系统呈现双稳态的参数空间区域中,鞍结流形、Hopf 流形和同宿流形均发生重复。

英文摘要:

Synchronization is an important phenomenon in a wide variety of systems comprising interacting oscillatory units, whether natural (like neurons, biochemical reactions, cardiac cells) or artificial (like metronomes, power grids, Josephson junctions). The Kuramoto model provides a simple description of these systems and has been useful in their mathematical exploration. Here we investigate this model combining two common features that have been observed in many systems: external periodic forcing and higher-order interactions among the elements. We show that the combination of these ingredients leads to a very rich bifurcation scenario that produces 11 different asymptotic states of the system, with competition between forced and spontaneous synchronization. We found, in particular, that saddle-node, Hopf and homoclinic manifolds are duplicated in regions of parameter space where the unforced system displays bi-stability.
