Xihao He, Xiaolu Tan, Jun Zou

AI总结:

本文提出并研究了Bank-El Karoui随机过程表示定理的均值场版本,建立了相关存在性与唯一性结果,并以此统一分析了含共同噪声和多种群的均值场博弈,同时给出了经典表示定理的稳定性结果。

摘要:

我们研究了Bank-El Karoui随机过程表示定理的均值场版本。在不同的技术条件下,我们建立了一些存在性和唯一性结果。作为动机和初步应用,我们的均值场表示结果提供了一种统一的方法,用于研究具有共同噪声和多种群设置下的不同均值场博弈(MFG),包括时机选择MFG、奇异控制MFG等。作为一个关键的技术步骤,我们给出了经典Bank-El Karoui表示定理的一个稳定性结果,该结果具有其自身的价值和其他应用,例如在推导一类最优停止问题和奇异控制问题的优化器(强意义下)的稳定性结果方面。

英文摘要:

We study a mean-field version of Bank-El Karoui's representation theorem of stochastic processes. Under different technical conditions, we establish some existence and uniqueness results. As motivation and first applications, our mean-field representation results provide a unified approach to study different Mean-Field Games (MFGs) in the setting with common noise and multiple populations, including the MFG of timing, the MFG with singular control, etc. As a crucial technical step, we provide a stability result on the classical Bank-El Karoui's representation theorem, which has its own interests and other applications, such as in deriving stability results of the optimizers (in the strong sense) for a class of optimal stopping problems and singular control problems.
