非Lipschitz聚集器随机递归控制问题的动态规划原理及相应的Hamilton-Jacobi-Bellman方程

Dynamic Programming Principle and Associated Hamilton-Jacobi-Bellman Equation for Stochastic Recursive Control Problem with Non-Lipschitz Aggregator

Jiangyan Pu, Qi Zhang

摘要:

本文研究了随机递归控制问题,其中描述运行费用的后向随机微分方程的聚集子(或称生成元)关于第一个未知变量和控制是连续的但不一定是Lipschitz的,并且关于第一个未知变量是单调的.在此基础上,利用倒向随机微分方程的广义比较定理和黏性解的稳定性,建立了动态规划原理以及相应的Hamilton-Jacobi-Bellman方程的值函数与粘性解之间的联系.最后以非Lipschitz聚集器的连续时间Epstein-Zin效用函数的控制问题为例说明了本文研究的应用。

英文摘要:

In this work we study the stochastic recursive control problem, in which the aggregator (or called generator) of the backward stochastic differential equation describing the running cost is continuous but not necessarily Lipschitz with respect to the first unknown variable and the control, and monotonic with respect to the first unknown variable. The dynamic programming principle and the connection between the value function and the viscosity solution of the associated Hamilton-Jacobi-Bellman equation are established in this setting by the generalized comparison theorem of backward stochastic differential equations and the stability of viscosity solutions. Finally we take the control problem of continuous-time Epstein-Zin utility with non-Lipschitz aggregator as an example to demonstrate the application of our study.
