Lévy稳定分布随机振子的自组织

Self-organisation of random oscillators with Lévy stable distributions

Sara Moradi, Johan Anderson

摘要:

提出了一种新的随机驱动振荡器自组织行为的可能性。结果表明,Lévy稳定过程的同步比具有高斯统计量的振子的同步有效得多。从尾部的分布函数的离群值事件的影响进行了检查,通过人工引入一些额外的振荡器具有非常强的耦合强度,它被发现,显着甚至一个这样的罕见和极端的事件可能会统治耦合系统的长期行为。除了乘性噪声分量,我们已经调查了外部的加性Lévy分布的噪声分量的振荡器的同步性能的影响。

英文摘要:

A novel possibility of self-organized behaviour of stochastically driven oscillators is presented. It is shown that synchronization by Lévy stable processes is significantly more efficient than that by oscillators with Gaussian statistics. The impact of outlier events from the tail of the distribution function was examined by artificially introducing a few additional oscillators with very strong coupling strengths and it is found that remarkably even one such rare and extreme event may govern the long term behaviour of the coupled system. In addition to the multiplicative noise component, we have investigated the impact of an external additive Lévy distributed noise component on the synchronisation properties of the oscillators.
