本文研究了随机环境中马氏链的状态性质,利用乘积空间的正则本质性和不可约性得到了随机环境中马氏链弱常返的充分条件.得到了随机环境中马氏链弱常返的充分条件.
we study some properties of states for Markov chains in random environments.Using the essence of the product space we obtain some examples to illustrate the properties.Then,using the irreducibility,we obtain some conditions for the MCRE to be weak recurrent.
