Stable determination of unbounded potential by asymptotic boundary spectral data

Yavar Kian, Éric Soccorsi

We consider the Dirichlet Laplacian $A_q=-\Delta +q$ in a bounded domain $\Omega \subset {\mathbb{R}}^d$, $d\ge 3$, with real-valued perturbation $q\in L^{\max (2,3d/5)}(\Omega )$. We examine th…
