一个等变常微分方程的异宿网络称为切换网络,如果它的每一个异宿轨迹序列都被附近的轨迹所遮蔽。如果这对正轨迹成立,则称之为前向转换。我们提供了一个切换鲁棒同宿网络的基本例子和一个前向切换渐近稳定的鲁棒同宿网络的相关例子。这些例子是五维等变常微分方程。
A heteroclinic network for an equivariant ordinary differential equation is called switching if each sequence of heteroclinic trajectories in it is shadowed by a nearby trajectory. It is called forward switching if this holds for positive trajectories. We provide an elementary example of a switching robust homoclinic network and a related example of a forward switching asymptotically stable robust homoclinic network. The examples are for five-dimensional equivariant ordinary differential equations.
