Within the class of stochastic processes one could say that markov chains are characterised by the dynamical property that they never look back. If there is only one communicating class that is, if every state is accessible from every other then the markov chain or its transition. Departing from the traditional combinatorial approach, in this article we present a simple unified approach for the distribution theory of runs based on a finite markov chain imbedding technique.
