令 G 为局部紧度量空间 E 的同胚正等连续流。我们展示了这种流的动力学是如何丰富的。我们研究 G 中的几乎周期性元素何时是周期性的,并描述轨道及其极限集。特别地,我们证明 G 的极限集 L(G ) 是一个闭子集,其中 G 是等连续的,并且如果 G 而且具有闭轨道,则任何 w 极限集都是周期轨道。
Let G be a positively equicontinuous flow of homeomorphisms of a locally compact metric space E. We show how the dynamics of such a flow are rich. We study when regularly almost periodic elements in G are periodic and we describe orbits and their limit sets. In particular, we show that the limit set L(G ) of G is a closed subset on which G is equicontinuous and that if G moreover has closed orbits, then any w-limit set is a periodic orbit.
