The Study Of Some Problems For Weakly Recurrence Of Markov Chains In Random Environments

This paper consists of three parts. In the first chapter , Markov double Chains are defined and some criteria is given. In the second chapter, we study weakly recurrence of the Markov in random environment, and provide the sufficient condition for weakly recurrence . In the third chapter, we study the classification of state space E by the basic theory of Markov Chains , partly generelize the conclusion for theory of classical Markov Chains.
