从无穷大到一:将一些平均场博弈简化为全局控制问题

From infinity to one: The reduction of some mean field games to a global control problem

Olivier Guéant

摘要:

本文介绍了最近的结果,从平均场博弈理论的基础上引入共同的噪音,强制将代理的分布作为一个状态变量。从J.M. Lasry和P.L.狮子和适应他们的游戏图,我们引入了一个偏微分方程,通常被称为主方程,从MFG方程可以推导出来。然后,这个主方程可以重新解释使用一个全局控制问题,诱导相同的行为,在非合作的初始平均场游戏。

英文摘要:

This paper presents recent results from Mean Field Game theory underlying the introduction of common noise that imposes to incorporate the distribution of the agents as a state variable. Starting from the usual mean field games equations introduced by J.M. Lasry and P.L. Lions and adapting them to games on graphs, we introduce a partial differential equation, often referred to as the Master equation, from which the MFG equations can be deduced. Then, this Master equation can be reinterpreted using a global control problem inducing the same behaviors as in the non-cooperative initial mean field game.
