英文摘要:
We study a robust Dynkin game over a set of mutually singular probabilities. We first prove that for the conservative player of the game, her lower and upper value processes coincide (i.e. She has a value process $V $ in the game). Such a result helps people connect the robust Dynkin game with second-order doubly reflected backward stochastic differential equations. Also, we show that the value process $V$ is a submartingale under an appropriately defined nonlinear expectations up to the first time $\\tau_*$ when $V$ meets the lower payoff process $L$. If the probability set is weakly compact, one can even find an optimal triplet. The mutual singularity of probabilities in causes major technical difficulties. To deal with them, we use some new methods including two approximations with respect to the set of stopping times. The mutual singularity of probabilities causes major technical difficulties.

中文摘要:
我们研究了一组相互奇异概率上的鲁棒Dynkin对策。我们首先证明,对于游戏中的保守玩家,她的上下价值过程是一致的(即她在游戏中有一个价值过程$V$)。这样的结果有助于人们将鲁棒Dynkin对策与二阶双反射倒向随机微分方程联系起来。此外,我们还证明了价值过程$V$在适当定义的非线性期望下是一个子鞅,直到$V$满足较低的支付过程$L$时第一次$\\tau_*$。如果概率集是弱紧的,我们甚至可以找到一个最优的三元组。概率的相互奇异性造成了重大的技术困难。为了解决这些问题,我们使用了一些新的方法,包括关于停止时间集的两种近似。概率的相互奇异性造成了重大的技术困难。为了解决这些问题,我们使用了一些新的方法,包括关于停止时间集的两种近似
