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 Hormander's famous "sums of squares" theorem.
