Abstract: We are interested in the ergodic and stochastic properties of dynamical systems preserving a infinite (sigma-finite) measure. We will investigate the notions of recurrence, ergodicity, mixing rate, law of large numbers, central limit theorems in this context, with illustrations on natural examples (billiards, intermittent maps). We will see strategies to establish these results using probability preserving dynamical systems (either via Z^d-extension or via induction).
