Question 2 Let (Xn)neNo be a time-homogeneous Markov process defined on a state space S with transition matrix P. For each state i E S let per(i) denote its period. Assume that S| 2 2 (meaning: there are at least two states). Moreover, assume that (Xn)nen, admits a limit distribution 7; := lim P[X, = i| Xo = j], i,j ES, 1-+00 which is uniquely determined by the equation . = TP. Then _ per(i) > 2. YES NO
