Reinforcement learning for irreversible reinsurance problems: the randomized singular control approach
Zongxia Liang, Xiaodong Luo, Xiang Yu
This paper studies the continuous-time reinforcement learning for stochastic singular control with the application to an infinite-horizon irreversible reinsurance problem. The sing…
Mean-Field Game of Relative Performance Portfolio for Two Populations with Poisson Common Noise
Yuchen Li, Zongxia Liang, Xiang Yu
This paper studies the mean field game (MFG) and N-player game on relative performance portfolio management with two heterogeneous populations. In addition to the Brownian idiosync…
Mean Field Game with Reflected Jump Diffusion Dynamics: A Linear Programming Approach
Zongxia Liang, Xiang Yu, Keyu Zhang
This paper develops a linear programming approach for mean field games with reflected jump-diffusion dynamics. We first prove the equivalence between the mean field equilibria in t…
A Reinforcement Learning Framework for Some Singular Stochastic Control Problems
Zongxia Liang, Xiaodong Luo, Xiang Yu
We develop a continuous-time reinforcement learning framework for a class of singular stochastic control problems without entropy regularization. The optimal singular control is ch…
Major-Minor Mean Field Game of Stopping: An Entropy Regularization Approach
Xiang Yu, Jiacheng Zhang, Keyu Zhang +1
This paper studies a discrete-time major-minor mean field game of stopping where the major player can choose either an optimal control or stopping time. We look for the relaxed equ…
