**Abstract:**

The paradigm of mean field games has been introduced to study games with a very large number of strategic agents. It relies on a combination of mean field theory and optimal control theory. The former, inspired by statistical physics, is useful to describe the state of the whole population. The latter provides a framework to study the behavior of a representative agent. The solution to a mean field game corresponds to a Nash equilibrium. It can be characterized using a forward- backward system of (partial or stochastic) differential equations. In the past decade, the theory of mean field games has been extensively developed. Furthermore, this paradigm has found many potential applications, from economics to sociology or distributed robotics. In this mini course, we will provide an overview of the following aspects of mean field games (tentative list):

1. Mean field games and mean field control problems

2. Partial differential equation viewpoint

3. Stochastic differential equation viewpoint

4. Numerical methods
