Abstract
In this paper, we study a strong limit theorem of delayed sums for Markov chains in bi-infinite environments by constructing a sequence of random variables with parameters. As a corollary, we obtain some strong limit properties including the generalized conditional relative entropy for Markov chains in bi-infinite random environment. The results which we obtained generalize the results of Liu et al. (Citation2015).
