  In this research paper, weighted / unweighted, directed / undirected graphs
are associated with interesting Discrete Time Markov Chains (DTMCs) as well as
Continuous Time Markov Chains (CTMCs). The equilibrium / transient behaviour of
such Markov chains is studied. Also entropy dynamics (Shannon entropy) of
certain structured Markov chains is investigated. Finally certain structured
graphs and the associated Markov chains are studied.
