For short we say (Xn)n?0is Markov(?P) Checking conditions (i) and (ii) is usually the most helpful way to determine whether or not a given random process (Xn)n?0is a Markov chain However it can also be helpful to have the alternative description which is provided by the following theorem Theorem 1 3
