平均场对策主方程的分裂方法与短时存在性

Splitting methods and short time existence for the master equations in mean field games

Pierre Cardaliaguet, Marco Cirant, Alessio Porretta

摘要:

我们开发了一个分裂的方法来证明的适定性,在短时间内,在平均场博弈(MFG)理论中的两个主方程的解决方案:二阶主方程,描述MFG与一个共同的噪音,和系统的主方程与MFG与一个主要的球员。这两个问题都是在概率测度空间中的无穷维方程。我们的新方法简化,缩短和推广以前存在的二阶主方程的结果,并提供了第一个存在的结果与MFG问题的系统与一个主要的球员。

英文摘要:

We develop a splitting method to prove the well-posedness, in short time, of solutions for two master equations in mean field game (MFG) theory: the second order master equation, describing MFGs with a common noise, and the system of master equations associated with MFGs with a major player. Both problems are infinite dimensional equations stated in the space of probability measures. Our new approach simplifies, shortens and generalizes previous existence results for second order master equations and provides the first existence result for systems associated with MFG problems with a major player.
