A Three-level Stochastic Linear-quadratic Stackelberg Differential Game with Asymmetric Information (2210.11808v1)

Abstract: This paper is concerned with a three-level stochastic linear-quadratic Stackelberg differential game with asymmetric information, in which three players participate credited as Player 1, Player 2 and Player 3. Player 3 acts as the leader of Player 2 and Player 1, Player 2 acts as the leader of Player 1 and Player 1 acts as the follower. The asymmetric information considered is: the information available to Player 1 is based on the sub-$\sigma$-algebra of the information available to Player 2, and the information available to Player 2 is based on the sub-$\sigma$-algebra of the information available to Player 3. By maximum principle of forward-backward stochastic differential equations and optimal filtering, feedback Stackelberg equilibrium of the game is given with the help of a new system consisting of three Riccati equations.
