异宿网络的可见性

Visibility of heteroclinic networks

Sofia B. S. D. Castro, Claire M. Postlethwaite, Alastair M. Rucklidge

AI总结:

本文指出传统稳定性概念不足以确定异宿网络附近轨迹的长期行为,为此引入了“可见性”概念,以精确指出瞬态衰减后可观察到的不变对象,并用文献中的例子加以说明。

摘要:

稳定性概念在动力系统领域有着悠久的历史:稳定的不变对象是在实验和数值模拟中预期会被观察到的对象。异宿网络是动力系统中与间歇性循环和切换行为相关的不变对象,在多种应用中均有发现。在本文中,我们指出,通常的稳定性概念,甚至是专门为异宿网络发展的稳定性概念,都不能提供确定异宿网络附近轨迹长期行为所需的所有信息。为了补充稳定性概念,我们引入了可见性的概念,它精确地指出了在瞬态衰减后将被观察到的不变对象。我们用文献中的异宿网络例子来说明我们的定义。

英文摘要:

The concept of stability has a long history in the field of dynamical systems: stable invariant objects are the ones that would be expected to be observed in experiments and numerical simulations. Heteroclinic networks are invariant objects in dynamical systems associated with intermittent cycling and switching behaviour, found in a range of applications. In this article, we note that the usual notions of stability, even those developed specifically for heteroclinic networks, do not provide all the information needed to determine the long-term behaviour of trajectories near heteroclinic networks. To complement the notion of stability, we introduce the concept of visibility, which pinpoints precisely the invariant objects that will be observed once transients have decayed. We illustrate our definitions with examples of heteroclinic networks from the literature.
