Characterization of Dirichlet-to-Neumann maps via the Born approximation

Carlos Castro, Fabricio Macià, Cristóbal Meroño +1

The problem of identifying the set of Dirichlet-to-Neumann (DtN) maps arising from conductivities on a smooth domain, among operators acting on functions on the boundary, is a chal…

The spectrum of Dirichlet-to-Neumann maps for radial conductivities

Thierry Daudé, Fabricio Macià, 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 Macià, 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-Neumann…

The Born approximation in the three-dimensional Calderón problem II: Numerical reconstruction in the radial case

Juan A. Barceló, Carlos Castro, Fabricio Macià +1

In this work we illustrate a number of properties of the Born approximation in the three-dimensional Calderón inverse conductivity problem by numerical experiments. The results are…

Rotational smoothing

Pedro Caro, Cristóbal J. Meroño, Ioannis Parissis

Rotational smoothing is a phenomenon consisting in a gain of regularity by means of averaging over rotations. This phenomenon is present in operators that regularize only in certai…

The fixed angle scattering problem with a first order perturbation

Cristóbal J. Meroño, Leyter Potenciano-Machado, Mikko Salo

We study the inverse scattering problem of determining a magnetic field and electric potential from scattering measurements corresponding to finitely many plane waves. The main res…

The observational limit of wave packets with noisy measurements

Pedro Caro, Cristóbal J. Meroño

The authors consider the problem of recovering an observable from certain measurements containing random errors. The observable is given by a pseudodifferential operator while the…

Optimal estimates for the double dispersion operator in backscattering

Cristóbal J. Meroño

We obtain optimal results in the problem of recovering the singularities of a potential from backscattering data. To do this we prove new estimates for the double dispersion operat…
