%0 Journal Article %T Some Limit Properties of Random Transition Probability for Second-Order Nonhomogeneous Markov Chains Indexed by a Tree %A Shi Zhiyan %A Yang Weiguo %J Journal of Inequalities and Applications %D 2009 %I Springer %X We study some limit properties of the harmonic mean of random transition probability for a second-order nonhomogeneous Markov chain and a nonhomogeneous Markov chain indexed by a tree. As corollary, we obtain the property of the harmonic mean of random transition probability for a nonhomogeneous Markov chain. %U http://www.journalofinequalitiesandapplications.com/content/2009/503203
