Code structure Mean-field game theory is the study of strategic decision making by small interacting agents in very large populations. Use of the term "mean field" is inspired by mean-field theory in physics, which considers the behaviour of systems of large numbers of particles where individual particles have negligible impact upon the system. Mean Field Games (MFGs) are games with a very large number of agents interacting in a mean field manner in such a way that each agent has a very small impact on the outcome. As a result, the game can be analyzed in the limit of an infinite number of agents.

Moll lecture in this A Mean Field Game (MFG) is a temporally extended decision making problem involving an inﬁnite number of identical and anonymous players. It can be solved by focusing on the optimal policy of a representative player in response to the behavior of the entire population. Let X and A be ﬁnite sets representing respectively the state and action This paper is concerned with the open-loop linear-quadratic (LQ) Stackelberg game of the mean-field stochastic systems in finite horizon. By means of two generalized differential Riccati equations, the follower first solves a mean-field stochastic LQ optimal control problem.

In the game theory and stochas-tic control literature, there are two very closely related modeling frameworks that are referred to as mean-field games andstationary mean-field games. We highlight the difference between these two modeling frameworks in Sec. 5.2. The current literature on using
These game situations, also referred to as mean-field-type games, involve novel equilibrium systems to be solved. Three solution approaches are presented: (ⅰ) dynamic programming principle, (ⅱ) stochastic maximum principle, (ⅲ) Wiener chaos expansion.

This is A mean ﬁeld game is a situation of stochastic (dynamic) decision making where I each agent interacts with the aggregate eﬀect of all other agents; I agents are non-cooperative.

Such models consider many individual components that interact with each other. In MFT, the effect of all the other individuals on any given individual is approximated by a single averaged effect, thus reducing a many-body problem to a one-body problem. The main idea of MFT is to Mean field term 可以做如下理解：每个参与者的状态是由随机变量刻画的，当参与者数量足够大的时候，总体的分布几乎就是每个参与者的概率分布。. Mean field games 的数学形式是一个耦合的偏微分方程组，即 Hamilton-Jacobi-Bellman 方程耦合上 Fokker-Planck 方程。.
