ABSTRACT

In this paper, we investigate reflected backward doubly stochastic differential equations (RBDSDEs) with a lower not necessarily right-continuous obstacle. First, we establish the existence and uniqueness of a solution to RBDSDEs with Lipschitz drivers. In the second part, we present a comparison theorem and we prove the existence of a minimal solution to the RBDSDE with the continuous driver.

具有不连续势垒的倒向倒向双随机微分方程

摘要

在本文中,我们研究了具有较低不一定右连续障碍物的反射后向双随机微分方程(RBDSDE)。首先,我们使用Lipschitz驱动程序确定RBDSDE解决方案的存在性和唯一性。在第二部分中,我们提出了一个比较定理,并证明了使用连续驱动器的RBDSDE的最小解的存在。
