不同Kuramoto振子的最佳频率同步网络

Optimally frequency synchronized networks of non identical Kuramoto oscillators

Lionel Gil

摘要:

基于局部贪婪数值算法,我们计算了同时满足两个条件的不同Kuramoto振子的加权、有向和无限扩展网络的拓扑:i)全局频率同步和ii)连接权的最小总质量.这个问题一直是以前许多有趣的研究的主题,但据我们所知,这是第一次没有先验约束,无论是在形式上还是在连接的动力学上。结果令人惊讶:最佳网络证明是强对称的、非常经济的,以显示强的丰富的俱乐部结构,并且除了已经报道的固有频率和传入连接的权重之间的强相关性之外,我们还观察到这些相同的固有频率和传出连接的权重之间的相关性,甚至更显著。后一个结果与理论预测不符。

英文摘要:

Based on a local greedy numerical algorithm, we compute the topology of weighted, directed, and of unlimited extension networks of non identical Kuramoto oscillators which simultaneously satisfy 2 criteria: i) global frequency synchronisation and ii) minimal total mass of the connection weights. This problem has been the subject of many previous interesting studies, but from our best knowledge, this is the first time that no a priori constraint is imposed, either on the form or on the dynamics of the connections. The results are surprising: the optimal networks turn out to be strongly symmetric, very economical, to display a strong rich club structure, and next to the already reported strong correlation between natural frequencies and the weight of incoming connections, we also observe a correlation, even more marked, between these same natural frequencies and the weight of outgoing connections. The latter result is at odds with theoretical predictions.
