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.
