It is proved that two sequences of Markov maps on the circle generated homeomorphic inverse limit spaces if each pair of the bounding maps with the same subscript are of the same Markov type with respect to a fixed arrangement of the two partitions.
证明了圆周上两个关于两组固定分点的Markov映射列在相同下标的两个约束映射总是关于两组分点的固定次序Markov同型的条件下生成同胚的逆极限空间。
Let f:S 1→S 1 be a continuous map of a circle S 1 into itself.
设f:S1 →S1 是圆周S1 上的连续自映射 ,本文证明 :如果f是 2 ∞ 型的混沌映射 ,那么f不具有伪轨跟踪性
