Markov chain mixing time

WebIf both i → j and j → i hold true then the states i and j communicate (usually denoted by i ↔ j ). Therefore, the Markov chain is irreducible if each two states communicate. It's an index. However, it has an interpretation: if be a transition probability matrix, then is the -th element of (here is a power).
