Title: Point process entropy and local energy

Abstract: My aim is to highlight some connections between stochastic processes, information theory, and statistical mechanics. After reviewing the classical Shannon--McMillan theorem, I will discuss the difficulties encountered in continuous time and/or state space, and indicate how they can be overcome. Then I will introduce the entropy of a point process, and explain in what sense the Poisson process may be regarded as a process with maximum entropy. If time permits, I may finally introduce the notion of Gibbs kernel, formalizing the notion of external conditioning, and give a precise meaning to the notion of local energy. (My discussion will mostly be elementary, and no special knowledge of physics is required.)
