justifying In this paper, we give explicit estimate on the rate of convergence of the transition probabilities to the stationary distribution for a class of exponential ergodic Markov chains. Our results are different from earlier estimates using coupling theory and from estimates using stochastically monotone. The estimates show a noticeable improvement on existing results if Markov chains contain instantaneous state or nonconservative state. The method of proof uses existing result of discrete time Markov chain, together with $h-$ skeleton. We apply this results, Ray-Knight compactification and $mbox{It}hat{o}$ excursion theory to two examples: a class of singular Markov chains and Kolmogorov matrix. In addition, we apply the Ray-Knight compactification, $mbox{It}hat{o}$ excursion theory and explicit estimate for convergence rates of continuous time markov chains to two examples: a class of singular Markov chains and Kolmogorovmatrix.
Keywords:exponential ergodicity; Markov chain; exponential ergodicity; Ray-Knight compactification; Poisson point process
