提升系统的逐点伪轨跟踪性质

Pseudo-orbit tracing property for lift systems

设X是紧度量空间，f：X→X是连续映射，又设~X是X的覆叠空间，~f：~X→~X是f的提升，证明了（~X，~f）有逐点伪轨跟踪性质，当且仅当（X，f）有逐点伪轨跟踪性质．

Suppose X is compact metric space ,f：X→X is continuous mapping,and suppose ~X is iterative space,~f：~X→~X is the lift of f. It is proved that the lift system （~x,~f） has the Pseudo - Orbit Tracing property if and only if（x,f） has the Pseudo - Orbit Tracing property .
