Jianjun Zhou

摘要:

本文引入了与路径依赖随机微分方程最优控制问题相关的二阶路径依赖Hamilton-Jacobi-Bellman(PHJB)方程黏性解的概念.我们将最优控制问题的值泛函确定为相应PHJB方程的唯一黏性解。我们还证明了我们的黏性解的概念与相应的经典解的概念是一致的,并且满足稳定性。应用倒向随机Hamilton-Jacobi-Bellman方程。

英文摘要:

In this article, a notion of viscosity solutions is introduced for second order path-dependent Hamilton-Jacobi-Bellman (PHJB) equations associated with optimal control problems for path-dependent stochastic differential equations. We identify the value functional of optimal control problems as unique viscosity solution to the associated PHJB equations. We also show that our notion of viscosity solutions is consistent with the corresponding notion of classical solutions, and satisfies a stability property. Applications to backward stochastic Hamilton-Jacobi-Bellman equations are also given.
