摘　　要：周期点集、回归点集、ω-极限集是动力系统中几个重要概念点集,回归点集、ω-极限集、非游荡点集的概念都是在周期点集概念的推广下得到的,都是动力系统中的重要点的集合.在周期点集的迭代不变性的研究下进一步讨论了回归点、ω-极限集的迭代不变性.The periodic point set, regression point set and ω-limit set are important conceptual point sets in dynamical system, the concept of regression point set, ω-limit set and non-wandering point set is obtained by the generalization of periodic point set concept and is the important point set in power system, this paper further discusses iterative invariance of regression point set and ω-limit set under the research on iterative invariance of periodic point set.

关 键 词：动力系统 周期点集 回归点集 Ω-极限集
