This paper is concerned with a linear-quadratic (LQ) stochastic Stackelberg differential game with one leader and two followers, where the game system is governed by a mean-field stochastic differential equation (MF-SDE). By maximum principle and verification theorem, the open-loop Stackelberg solution is expressed as a feedback form of the state and its mean with the help of three systems of Riccati equations.

具有一个领导者和两个跟随者的均场线性二次随机Stackelberg微分游戏

本文涉及具有一个领导者和两个跟随者的线性二次（LQ）随机Stackelberg微分游戏，其中该游戏系统由均场随机微分方程（MF-SDE）控制。根据最大原理和验证定理，借助三个Riccati方程组，开环Stackelberg解表示为状态及其均值的反馈形式。
