摘要

In this paper, we define multi-leader–follower Bayesian games by considering incomplete information among the followers. We then propose an equilibrium concept for such games and demonstrate the existence of equilibrium using the Fan-Glicksberg fixed point theorem. Furthermore, we show the structural stability and robustness of \(\varepsilon \) -equilibria when both the payoff functions and the players’ information are perturbed simultaneously.
