报告题目：Two-person zero-sum risk-sensitive stochastic games with incomplete information

报告摘要：This talk is on two-person zero-sum risk-sensitive discrete-time s- tochastic games with incomplete reward information on one side. We prove the existence of the value function, derive a new Shapley equation by introducing a functional of re- wards, and prove that the value function solves the Shapley equation, which is used to construct an optimal policy for the informed player. To show the existence of an optimal policy for the uninformed player, we introduce auxiliary dual risk-sensitive games and construct an optimal policy for the uninformed player in the primal games by the optimal policies in the dual games. Finally, we give an example to illustrate effects of the reward information and risk-sensitive parameters on the value and optimal policies of the games.
