摘要:

我们提出了一个统计分析的基础上的高度和返回时间的概率高振幅波事件的聚焦和散焦Manakov系统。我们发现,分析理性/半理性的解决方案,与极端,流氓波(RW)的结构,是领先的高振幅事件在这个系统中。我们定义的阈值分类为RW的极端波事件。我们的研究结果表明,有一个强大的RW和负责其创建的机制之间的关系。最初,高振幅事件起源于调制不稳定性。在随后的演化中,这些事件之间的相互作用作为RW创建的机制而占主导地位。我们提出了一种新的策略,以确认不同的极端事件的基本属性。这涉及在RW动态的每个阶段确定适当的统计措施。我们的研究结果指出,需要定义新的标准,以确定RW事件。

英文摘要:

We present a statistical analysis based on the height and return time probabilities of high amplitude wave events in both focusing and defocusing Manakov systems. We find that analytical rational/semirational solutions, associated with extreme, rogue wave (RW) structures, are the leading high amplitude events in this system. We define the thresholds for classifying an extreme wave event as a RW. Our results indicate that there is a strong relation between the type of the RW and the mechanism which is responsible for its creation. Initially, high amplitude events originate from modulation instability. Upon subsequent evolution, the interaction among these events prevails as the mechanism for RW creation. We suggest a new strategy for confirming the basic properties of different extreme events. This involves the definition of proper statistical measures at each stage of the RW dynamics. Our results point to the need for defining new criteria for identifying RW events.
