英文摘要:
We consider the optimal stopping problem with non-linear $f$-expectation (induced by a BSDE) without making any regularity assumptions on the reward process $\\xi$. and with general filtration. We show that the value family can be aggregated by an optional process $Y$. We characterize the process $Y$ as the $\\mathcal{E}^f$-Snell envelope of $\\xi$. We also establish an infinitesimal characterization of the value process $Y$ in terms of a Reflected BSDE with $\\xi$ as the obstacle. To do this, we first establish a comparison theorem for irregular RBSDEs. We give an application to the pricing of American options with irregular pay-off in an imperfect market model.

中文摘要:
我们考虑了具有非线性$f$-期望(由BSDE诱导)的最优停止问题,没有对奖励过程$\\ xi$作任何正则性假设。和一般过滤。我们证明了价值族可以通过可选的进程$Y$聚合。我们将过程$Y$描述为$\\ xi$的$\\数学{E}^f$-斯内尔包络。我们还建立了以$\\ xi$为障碍的反射BSDE的价值过程$\\ Y$的无穷小特征。为此,我们首先建立了不规则RBSDE的比较定理。在不完全市场模型下,我们给出了不规则支付美式期权定价的一个应用。
