随机迁移方程的精确能控性

Exact Controllability for Stochastic Transport Equations

Qi Lü

摘要:

本文研究了随机迁移方程的精确能控性问题,通过对漂移项施加边界控制和对扩散项施加内部控制来实现.通过对偶性论证,该能控性问题可化为倒向随机迁移方程的能观性问题,并通过一个新的整体Carleman估计得到所需的能观性估计.此外,我们提出了一些结果缺乏精确可控性,这表明两个控制的行动是必要的。在某种程度上,这表明随机偏微分方程的可控性问题不同于确定性偏微分方程。

英文摘要:

This paper is addressed to studying the exact controllability for stochastic transport equations by two controls: one is a boundary control imposed on the drift term and the other is an internal control imposed on the diffusion term. By means of the duality argument, this controllability problem can be reduced to an observability problem for backward stochastic transport equations, and the desired observability estimate is obtained by a new global Carleman estimate. Also, we present some results about the lack of exact controllability, which show that the action of two controls is necessary. To some extent, this indicates that the controllability problems for stochastic PDEs differ from their deterministic counterpart.
