关于一个Robin谱逆问题

On an inverse Robin spectral problem

Matteo Santacesaria, Toshiaki Yachimura

摘要:

本文考虑由有界区域$Ω$的边界上Laplace算子的Dirichlet边界条件的主特征值和主特征函数的法向导数的边值求出$Ω$的边界的一部分$γ\subset \partial Ω$上的Robin系数的问题.我们证明了唯一性,以及局部Lipschitz稳定的反问题。此外,我们提出了一个迭代重建算法与数值计算在二维显示的方法的准确性。

英文摘要:

We consider the problem of the recovery of a Robin coefficient on a part $γ\subset \partial Ω$ of the boundary of a bounded domain $Ω$ from the principal eigenvalue and the boundary values of the normal derivative of the principal eigenfunction of the Laplace operator with Dirichlet boundary condition on $\partial Ω\setminus γ$. We prove uniqueness, as well as local Lipschitz stability of the inverse problem. Moreover, we present an iterative reconstruction algorithm with numerical computations in two dimensions showing the accuracy of the method.
