具有部分信息流的最优停止、随机停止和奇异控制

Optimal stopping, randomized stopping and singular control with partial information flow

Nacira Agram, Sven Haadem, Bernt Oksendal, Frank Proske

摘要:

本文的目的是双重的:我们延长了著名的最佳停止和随机停止一个给定的随机过程的情况下,可用的信息流是一个过滤没有先验假设的过滤过程之间的关系。我们称这些问题为最优停止和随机停止一般信息。遵循Krylov [K]的思想,我们引入了一个特殊的具有一般信息的奇异随机控制问题,并证明这也等价于部分信息最优停止和随机停止问题。然后我们证明了这个奇异控制问题的解可以用部分信息变分不等式表示。

英文摘要:

The purpose of this paper is two-fold: We extend the well-known relation between optimal stopping and randomized stopping of a given stochastic process to a situation where the available information flow is a filtration with no a priori assumed relation to the filtration of the process. We call these problems optimal stopping and randomized stopping with general information. Following an idea of Krylov [K] we introduce a special singular stochastic control problem with general information and show that this is also equivalent to the partial information optimal stopping and randomized stopping problems. Then we show that the solution of this singular control problem can be expressed in terms of partial information variational inequalities.
