Consider the Markov chain with transition matrix in Exercise, with [math]a = b = 1[/math]. Show that this chain is ergodic but not regular.

Find the fixed probability vector and interpret it. Show that [math]\mat {P}^n[/math] does not tend to a limit, but that

[[math]] \mat {A}_n = \frac{\mat {I} + \mat {P} + \mat {P}^2 +\cdots + \mat {P}^n}{n + 1} [[/math]]

does.
