分数阶扩散(波动)方程的运动源反问题:轨道的确定

Inverse moving source problem for fractional diffusion(-wave) equations: Determination of orbits

Guanghui Hu, Yikan Liu, Masahiro Yamamoto

摘要:

本文研究了在$\mathbb R^d$的连通有界区域或整个空间$\mathbb R^d$中分数阶扩散(-波)方程运动源轨道的反问题.基于一个新建立的分数阶Duhamel原理,利用$d$内点的观测数据,得到了局部运动源情况下的Lipschitz稳定性估计.一般非定域运动源的唯一性用更多内部观测的附加数据进行了验证。

英文摘要:

This paper is concerned with the inverse problem on determining an orbit of the moving source in a fractional diffusion(-wave) equations in a connected bounded domain of $\mathbb R^d$ or in the whole space $\mathbb R^d$. Based on a newly established fractional Duhamel's principle, we derive a Lipschitz stability estimate in the case of a localized moving source by the observation data at $d$ interior points. The uniqueness for the general non-localized moving source is verified with additional data of more interior observations.
