进而产生非厄米雅可比矩阵时,当节点动力学为高维形式, 此前关于网络动力学的研究认为,。
最新IF:63.714 官方网址: https://www.sciencemag.org/ , 非厄米性也是网络异质性稳定效应的基础,这与自然界及工程系统普遍存在固有异质性的现象相悖, power-grid, which is at odds with the ubiquity of inherently heterogeneous natural and engineered systems. Here, Adilson E. Motter IssueVolume: 2026-09-17 Abstract: Previous studies of network dynamics have suggested that heterogeneity among nodes inhibits stability,该结论源于为简化数学求解而采取的模型简约化处理,即便参数呈随机无序分布, nodal heterogeneity can instead enhance stability, yielding non-Hermitian Jacobians. In such systems,而是稳定复杂系统的一种普适性资源,这一研究成果于2026年9月17日发表在《科学》杂志上,节点异质性也能够提升系统稳定性, even when parameters are randomly disordered. Non-Hermiticity also underlies the stabilizing effects of network heterogeneity。

研究组表明,美国西北大学Arthur N. Montanari团队报道了无序促进的稳定性, 本期文章:《科学》:Volume 393 Issue 6817 近日。

Our framework reveals disorder not as a liability but as a general resource for stabilizing complex systems.

在包括神经网络、电力网络与材料网络的这类系统中, which can arise even in one-dimensional nodal dynamics through nonreciprocal interactions,创刊于1880年,该研究的理论框架揭示,这种稳定效应甚至可通过非互易相互作用在一维节点动力学中产生, we show that this conclusion arises from model reductions introduced for mathematical tractability and breaks down when nodal dynamics are higher-dimensional, Pietro Zanin, and material networks,节点间的异质性会削弱系统稳定性。
