摘要
讨论了随机环境马氏链中具有强π-不可约性链的常返性的判定,从而得到了强π-不可约链常返性判定的充分必要条件,同时首次提出了关于单链X→的弱不变测度的概念.
In this paper, recurrence of strongly π-irreducible Markov chains in random environment is discussed, then a criterion for recurrece of strongly π-irreducible Markov chains in random environments is obtained. The concept of weakly invariant measure of single chain X→ is firstly put forward.=
