Abstract. Let {X"; n > 0} be a Harris-recurrent Markov chain on a general state space. It is shown that there is a sequence of random times {N¡; i > 1} such that {XN.; i > 1} are independent and identically distributed. This idea is used to show that {Xn} is equivalent to a process having a recurrence point, and to develop a regenerative scheme which leads to simple proofs of the ergodic theorem, existence and uniqueness of stationary measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
