Issue: Updated version of the solutions to exercises in Norris, Markov Chains

Type of course: standard

Exercise: Suggested exercises from Chapter 6, Grimmett and Stirzaker:6.1 - n. 2,3,8,9,10,11 e 12, 6.2 - 2,4, 6.3 - 1 e 3 (without mean recurrence time),2,4 (simplify the chain),5,8 e 10 (first part).

Examination tests:

Knowledge and understanding:
Students have to acquired familiarity with Markov stochastic processes, thought of as random dynamical systems with loss of memory. At the end of the course, students will be able to deal with concepts as recurrence, transience, reversibility, stationarity, convergence to equilibrium, stopping time, Markov property.

Skills and attributes:
Successful students will be able to model concrete phenomena by means of Markov stochastic process, as in queuing and biological applications, to determine the asymptotic behavior and dynamical features as transience and recurrence, to compute possible invariant and reversible distributions.

Personal study: the percentage of personal study required by this course is the 65% of the total.
