- G63.2931.001 ADVANCED TOPICS IN PROBABILITY (Markov
Processes and Diffusions).
In the first part of the course, we will give an introduction to
the general theory of Markov processes for both discrete and
continuous time. Our main focus will be the study of their
long-time behavior (transience, recurrence, ergodicity, mixing)
in the classical context of Harris chains, but also for a larger
class of processes that doesn't fit into this context. The
second part of the course will be aimed at applying the abstract
results from the first part to the more concrete framework of
elliptic diffusion processes. Lyapunov function techniques will
play a prominent role in this part of the course. The final part
of the course will be an introduction to the theory of
hypoelliptic diffusion processes. We will give a short
introduction to Mallivain calculus and use it to give a
probabilistic proof of Hörmander's famous "sums of squares"
