Closed-loop $\alpha$-Potential Stochastic Differential Games via a BSDE Approach
In this paper, we study the closed-loop $\alpha $-potential stochastic differential game (SDG) problem as a continuation of our prior research on open-loop control (see \cite{GLZ2025}). By utilizing the backward stochastic differential equation (BSDE) approach, we derive a precise estimate for the parameter $\alpha $....
