Global counterexamples to uniqueness for a Calderón problem with $C^{k}$ conductivities

Thierry Daudé, Bernard Helffer, Niky Kamran +1

Let $Ω \subset R^{n}$ , $n \geq 3$ , be a fixed smooth bounded domain, and let $γ$ be a smooth conductivity in $Ω$ . Consider a non-zero frequency $λ_{0}$ which does not belong to…

Stable factorization of the Calderón problem via the Born approximation

Thierry Daudé, Fabricio Macià, Cristóbal Meroño +1

In this article, we prove the existence of the Born approximation in the context of the radial Calderón problem for Schrödinger operators. The Born approximation naturally appears…
