WebThis means that, if one of the states in an irreducible Markov Chain is aperiodic, say, then all the remaining states are also aperiodic. Since, p a a ( 1) > 0, by the definition of periodicity, state a is aperiodic. As the given Markov Chain is irreducible, the rest of the states of the Markov Chain are also aperiodic. http://eaton.math.rpi.edu/CourseMaterials/Spring2010/PK6790/stochnotes032310.pdf Webone communication class C= f1;2;3;4g= S: all states communicate.

WebCommunication Classes The set of equivalences classes in a DTMC are the communication classes. If every state in the Markov chain can be reached by every other state, then there is only one communication class. Irreducible If there is only one communication class, then the Markov chain is irreducible, otherwise is it reducible.
