Stationary Markov Equilibria for K-Class Discounted Stochastic Games
For a discounted stochastic game with an uncountable state space and compact metric action spaces, we show that if the measurable-selection-valued...
A Fixed Point Theorem for Measurable-Selection-Valued Correspondences Arising in Game Theory
