Web11 feb. 2024 · A Markov chain is called a regular chain if some power of the transition matrix has only positive elements. It appears to me they are equivalents: If a Markov chain is regular, then some power of the transition matrix has only positive elements, which implies that we can go from every state to any other state. Web25 apr. 2015 · Let Y t = 1 if X t ≠ 0; Y t = 0 if X t = 0. This is a 2 states Markov chain; 0 is recurrent for X iff it is recurrent for Y. For this Markov chain, the distribution of the time of return to 0 is a geometric law; it is almost always finite. Hence the chain is recurrent.
