正则与奇异组合随机控制问题的BSDE形式

BSDE formulation of combined regular and singular stochastic control problems

Bruno Bouchard, Patrick Cheridito, Ying Hu

摘要:

本文研究了一类正则与奇异组合的随机控制问题,它可以表示为约束倒向随机微分方程。在马尔可夫的情况下,这通过具有梯度约束的偏微分方程简化为特征。但是,贝加尔公式使得超越马尔可夫模型并考虑路径依赖问题成为可能。我们还提供了一个近似的原始控制问题与标准的BSDES,产生一个表征近似最优值和控制。

英文摘要:

In this paper we study a class of combined regular and singular stochastic control problems that can be expressed as constrained BSDEs. In the Markovian case, this reduces to a characterization through a PDE with gradient constraint. But the BSDE formulation makes it possible to move beyond Markovian models and consider path-dependent problems. We also provide an approximation of the original control problem with standard BSDEs that yield a characterization of approximately optimal values and controls.
