AI总结:

研究揭示了有向Kuramoto网络中相锁定状态的稳定性受网络结构与适应性耦合动态的共同影响,显示静态结构限制稳定性,而适应性动态增强其鲁棒性。

摘要:

适应性Kuramoto模型允许存在多种非平凡的相锁定配置,包括反向和旋转波状态。一个核心的开放性问题是,观察到的这些配置的持续性是否可以归因于相关有向相互作用网络的内在性质,还是主要依赖于适应性耦合动态。为了解决这个问题,我们研究了在固定有向网络上抗相位和旋转波相配置的稳定性,这些网络保持相同的相位对称性,但不是由适应性动态生成的。我们显示,对于两种标准的静态有向网络,稳定性受到严格限制,不稳定模式在参数变化下普遍持续存在,并且我们描述了适应性耦合如何影响配置中允许稳定性的不变集和吸引盆地。总的来说,这些结果表明,尽管静态网络结构对相锁定配置的稳定性施加了严格限制,但当稳定性被允许时,适应性耦合动态会组织和界定其鲁棒性。

英文摘要:

Adaptive Kuramoto models admit a variety of nontrivial phase-locked configurations, including antipodal and rotating-wave states. A central open question is whether the observed persistence of such configurations can be attributed to intrinsic properties of the associated signed interaction networks, or whether it relies essentially on adaptive coupling dynamics. To address this question, we study the stability of antipodal and rotating-wave phase configurations on fixed signed networks that preserve the same phase symmetries but are not generated by adaptive dynamics. We show that for two canonical classes of static signed networks, stability is highly constrained, with unstable modes persisting under parameter variations generically, and we characterize how adaptive coupling influences invariant sets and basins of attraction for the configurations where stability is permitted. Taken together, these results show that while static network structure imposes severe constraints on the stability of phase-locked configurations, adaptive coupling dynamics organize and delineate their robustness when stability is permitted.
