摘要
研究了可降映射的极小性、拓扑传递性、拓扑混合性。证明了若可降映射是极小性的、拓扑传递的、拓扑混合的当且仅当它的下降组各个映射是极小的、拓扑传递的、拓扑混合的。
In this paper,the minimality,topological transitivity and topological mixing of descendible mappings were discussed.It was proved that descendible mapping is minimality,topological transitivity and topological mixing,if and only if the mappings of descendible group of descendible mappings,are minimality,topological transitivity and topological mixing.
