A Geometric Inverse Source Problem for Stochastic Parabolic Equations
Yunzhang Li, Qi Lü, Meizhi Qian +1
This paper addresses the geometric inverse problem of simultaneously recovering two unknown deterministic source supports in a stochastic parabolic equation, where one source appea…
Stability Estimate for an Inverse Stochastic Parabolic Problem of Determining Unknown Time-varying Boundary
Zhonghua Liao, Qi Lü
Stochastic parabolic equations are widely used to model many random phenomena in natural sciences, such as the temperature distribution in a noisy medium, the dynamics of a chemica…
Stochastic Verification Theorem for Infinite Dimensional Stochastic Control Systems
Liangying Chen, Qi Lü
The verification theorem serving as an optimality condition for the optimal control problem, has been expected and studied for a long time. The purpose of this paper is to establis…
Optimal Feedback Controls of Stochastic Linear Quadratic Control Problems in Infinite Dimensions with Random Coefficients

It is a longstanding unsolved problem to characterize the optimal feedback controls for general linear quadratic optimal control problem of stochastic evolution equation with rando…
Relationships Between the Maximum Principle and Dynamic Programming for Infinite Dimensional Stochastic Control Systems
Liangying Chen, Qi Lü
Pontryagin type maximum principle and Bellman's dynamic programming principle serve as two of the most important tools in solving optimal control problems. There is a huge literatu…
Null controllability for stochastic fourth order parabolic equations
Qi Lü, Yu Wang
We establish the null controllability for linear stochastic fourth order parabolic equations. Utilizing the duality argument, the null controllability is reduced to the observabili…
