摘要
研究了一个动力系统能够被提升为Markov链的必要条件 .证明了一个系统如果能够被特征映射提升为Markov链时 ,它必须是可扩的且具有伪轨追踪性 .
The problem of when a dynamical system can be lifted to a Markov subshift is considered. It is proved that if it can be lifted by a so called characteristic map it should be expansive and has the pseudo orbit tracing property.
