摘要翻译:
我们提出了一种方法,可以在耦合混沌振子中识别相位同步,而不必显式测量相位。我们证明,如果一个人在一个振子中定义一个典型事件,然后每当这个事件发生时观察另一个振子,这些观察就产生了一个局部集。我们的结果提供了一种通用而简单的方法来识别PS,这种方法也适用于具有多个时间尺度的振荡器。我们在化学耦合神经元网络中说明了我们的方法。我们发现,在整个网络中,同步神经元在同步开始之前就会形成一簇同步神经元,为信息交换提供了一个合适的环境。此外,我们给出了局域集与耦合混沌振子所能交换的信息量之间的关系。

英文摘要:
  We present an approach which enables to identify phase synchronization in coupled chaotic oscillators without having to explicitly measure the phase. We show that if one defines a typical event in one oscillator and then observes another one whenever this event occurs, these observations give rise to a localized set. Our result provides a general and easy way to identify PS, which can also be used to oscillators that possess multiple time scales. We illustrate our approach in networks of chemically coupled neurons. We show that clusters of phase synchronous neurons may emerge before the onset of phase synchronization in the whole network, producing a suitable environment for information exchanging. Furthermore, we show the relation between the localized sets and the amount of information that coupled chaotic oscillator can exchange.
