Stable factorization of the Calderón problem via the Born approximation
Thierry Daudé, Fabricio MaciÃ, 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 appear…

The spectrum of Dirichlet-to-Neumann maps for radial conductivities
Thierry Daudé, Fabricio MaciÃ, Cristóbal Meroño +1
The problem of characterizing sequences of real numbers that arise as spectra of Dirichlet-to-Neumann (DtN) maps for elliptic operators has attracted considerable attention over th…

The Born approximation for the fixed energy Calderón problem
Fabricio MaciÃ, Cristóbal Meroño, Daniel Sánchez-Mendoza
The Born approximation of a potential in the context of the Calderón inverse problem is an object that can be formally defined in terms of spectral data of the Dirichlet-to-Neuman…
