WebIf we have an irreducible Markov chain, this means that the chain is aperiodic. Since the number 1 is co-prime to every integer, any state with a self-transition is aperiodic. If there is a self-transition in the chain (pii>0 for some i), then the chain is aperiodic. Web2. Markov Chains and Harris Recurrence. Consider a Markov chain {X n} with transition probabilities P(x,·), on a state space X with σ-algebra F. Let Pn(x,·) be the n-step transition kernel, and for A ∈ F, let τ A = inf{n≥ 1 : X n ∈ A} be the ﬁrst return time to A, with τ A = ∞ if the chain never returns to A.
