不同Kuramoto振子的同步优化网络

Synchrony-optimized Networks of Non-identical Kuramoto Oscillators

Markus Brede

摘要:

在这封信中,我们讨论了一种方法,用于生成同步优化的耦合结构的Kuramoto振荡器与异质分布的固有频率。该方法允许我们将耦合网络的性质与其同步性联系起来。这些关系以前只建立从一个线性稳定性分析相同的振荡器的情况下。我们进一步证明,在振荡器人口的异质性产生异质性的最佳耦合网络以及。给出了通过适当地放置振荡器来增强给定网络的同步性的两个规则:(i)相邻振荡器的固有频率必须是反相关的;(ii)频率幅度应该与它们所放置的节点的度正相关。

英文摘要:

In this letter we discuss a method for generating synchrony-optimized coupling architectures of Kuramoto oscillators with a heterogeneous distribution of native frequencies. The method allows us to relate the properties of the coupling network to its synchronizability. These relations were previously only established from a linear stability analysis of the identical oscillator case. We further demonstrate that the heterogeneity in the oscillator population produces heterogeneity in the optimal coupling network as well. Two rules for enhancing the synchronizability of a given network by a suitable placement of oscillators are given: (i) native frequencies of adjacent oscillators must be anti-correlated and (ii) frequency magnitudes should positively correlate with the degree of the node they are placed at.
