Books

  • Sheldon M. Ross. Introduction to probability models. Academic Press, New York, 2003
    The course is based on this book. The book also contains most of the homework problems.
  • Rick Durrett. Essentials of stochastic processes. Springer 1999
    Elegant rigorous treatment of most of the topics
  • James R. Norris. Markov Chains. Cambridge University Press, 1997.
    Classical reference on Markov chains
  • David Aldous and James A. Fill. Reversible Markov Chains and Random Walks on Graphs. Available here .
    Advanced book on Markov chains. Highly recommended, in particular, if you've got a feeling that this all is too easy!
  • Sheldon M. Ross. Stochastic processes. Wiley, New York, 1996..
    Very good book on stochastic processes, covering most of the material, slightly more advanced than `Introduction to Probability Models'
  • William J. Stewart (1994) An Introduction to the Numerical Solution of Markov Chains. Princeton University Press
    The classical reference if you need to find a stationary distribution of a large Markov Chain by using numerical methods
