Abeer Aldoghaither, Taous-Meriem Laleg-Kirati, Da-Yan Liu

摘要:

本文研究了有限区域上空间分数阶对流扩散方程的正问题和反问题。反问题在于从最终观测值确定源项。我们首先驱动的基本解的直接问题,我们表明,源和最终观察之间的关系是线性的。此外,我们还研究了这两个问题的适定性:存在性、唯一性和稳定性。最后,我们用一个数值例子来说明结果。

英文摘要:

In this paper, direct and inverse problems for a space fractional advection dispersion equation on a finite domain are studied. The inverse problem consists in determining the source term from a final observation. We first drive the fundamental solution to the direct problem and we show that the relation between source and the final observation is linear. Moreover, we study the well-posedness of both problems: existence, uniqueness and stability. Finally, we illustrate the results with a numerical example.
