用渐近边界谱数据稳定确定无界势

Stable determination of unbounded potential by asymptotic boundary spectral data

Yavar Kian, Éric Soccorsi

摘要:

本文研究了有界区域$Ω\subset \mathbb{R}^d$,$d \ge 3$中的Dirichlet Laplacian $A_q=-Δ+q$,其中$A_q=-Δ+q$具有实值扰动$q \in L^{\max(2 , 3 d / 5)}(Ω)$ .我们研究的稳定性问题的反问题,确定电位$q$的$A_q$的特征值的渐近行为。假设在$L^2(\partial Ω)$中本征函数的法向导数的边界测量是平方可和序列,我们证明了通过本征值的渐近性知识,可以Hölder稳定地恢复$q$

英文摘要:

We consider the Dirichlet Laplacian $A_q=-Δ+q$ in a bounded domain $Ω\subset \mathbb{R}^d$, $d \ge 3$, with real-valued perturbation $q \in L^{\max(2 , 3 d / 5)}(Ω)$. We examine the stability issue in the inverse problem of determining the electric potential $q$ from the asymptotic behavior of the eigenvalues of $A_q$. Assuming that the boundary measurement of the normal derivative of the eigenfunctions is a square summable sequence in $L^2(\partial Ω)$, we prove that $q$ can be Hölder stably retrieved through knowledge of the asymptotics of the eigenvalues
