定义了随机环境中马氏链的强π-不可约性;给出了一个非正则本质状态不存在的充分条件;得出了在各种不可约性的条件下,状态的各种性质;研究了随机环境中马氏链的各种特性函数的性质.
We define the strong π-irreducibility for Markov chains in random environments. A sufficient condition is obtained to ensure no improperly essential state existing. We obtain many properties of states under various irreducibilities. Finally, we study the properties of various character functions for Markov chains in random environments.
