研究了非对称随机网络中脉冲耦合振子系统的集体同步。我们证明,随机矩阵理论可以用来准确地预测在这样的网络中的同步速度的动力学和网络参数的依赖。此外,我们表明,同步的速度是有限的网络连接,并保持有限的,即使耦合强度变得无限大。此外,我们的研究结果表明,同步是强大的结构扰动下的网络动力学。
We study collective synchronization of pulse-coupled oscillators interacting on asymmetric random networks. We demonstrate that random matrix theory can be used to accurately predict the speed of synchronization in such networks in dependence on the dynamical and network parameters. Furthermore, we show that the speed of synchronization is limited by the network connectivity and remains finite, even if the coupling strength becomes infinite. In addition, our results indicate that synchrony is robust under structural perturbations of the network dynamics.
