摘要

In this paper, we study two-person zero-sum stochastic games with stopping and control for semi-Markov processes on a Borel state space under a risk-sensitive discounted cost criterion. In this framework, at each decision epoch, both players may either take an action or stop the game. Under suitable assumptions, we deduce that the game has a value obtained as the unique solution of certain dynamic programming inequalities with bilateral constraints. Moreover, we are able to show the existence of a saddle point equilibrium.
