引入了随机环境中马氏链的状态周期,研究了周期的一些性质,在假定状态周期存在的条件下,研究了一个未解决问题(Orey,1991;问题1.3.3).
The periods of states for Markov chains in a random environment are introduced and some properties about periods are investigated. An open problem (Orey, 1991; Problem 1.3.3) is studied under the assumption that states have periods.
