potp

Equicontinuity and POTP proximally continuous set-valued maps

等度连续与POTP集值邻近连续映射

In section 2.3 , it is proved that a equicontinuous self-mapping of a compact and connected metric space can not have the POTP .

3节证明了紧致连通的度量空间上的等度连续自映射不具有伪轨跟踪性。

Let f be a homeomorphism , the following statements were obtained : if f is distal and has POTP , then fn does not have the average shadowing property ;

设f是个同胚映射，得到了如下结果：若f有POTP且是distal的，则fn不具有平均跟踪性；

Objective : To investigate correct management modes and the effects on mothers and neonates of fetal persistent occiput transverse position ( POTP ) and persistent occiput posterior position ( POPP ) .

目的：探讨持续性枕横（后）位正确的处理方式及其对母婴的影响。

In section 2.4 , a sufficient condition is given for a distal homeomorphism not having the POTP . In the end of this section , we describe the distal homeomorphism s of intervals and circles .

4节给出了紧致度量空间上的distal自同胚不具有伪轨跟踪性的一个充分条件，并给出了区间上和圆周上distal同胚的等价刻划。

Specification is an important dynamical property , and it is equivalent to topological mixing for continuous mapping on the interval and the tree , and for the continuous map of compact metric space , POTP and topological mixing imply weak specification .

specification性质是一种重要的动力性质，对连续的区间映射和树映射，该性质与拓扑混合等价。对紧致度量空间，满足POTP性质的拓扑混合映射具有specification性质。
