$\mathbb{R}^4$中异宿网络的构造

Construction of heteroclinic networks in $\mathbb{R}^4$

Alexander Lohse, Sofia B. S. D. Castro

摘要:

我们研究了$\mathbb{R}^4$中的异宿网络,它是由某种简单的鲁棒异宿环构成的。在二维不动点空间中,单圈中的所有联络都是鞍汇型的。我们发现,只有很少的方法加入这样的循环在一起的网络,并提供了所有可能的网络在$\mathbb{R}^4$的列表。网络涉及简单的异宿周期的A型是新的文献中,我们描述了这些网络中的周期的稳定性:虽然A型和B型网络的几何形状是非常相似的,稳定性区分它们清楚。

英文摘要:

We study heteroclinic networks in $\mathbb{R}^4$, made of a certain type of simple robust heteroclinic cycle. In simple cycles all the connections are of saddle-sink type in two-dimensional fixed-point spaces. We show that there exist only very few ways to join such cycles together in a network and provide the list of all possible such networks in $\mathbb{R}^4$. The networks involving simple heteroclinic cycles of type A are new in the literature and we describe the stability of the cycles in these networks: while the geometry of type A and type B networks is very similar, stability distinguishes them clearly.
