Several applications in medical imaging and non-destructive material testing lead to inverse elliptic coefficient problems, where an unknown coefficient function in an elliptic PDE is to be determined from partial knowledge of its solutions. This is usually a highly non-linear ill-posed inverse problem, for which unique reconstructability results, stability estimates and global convergence of numerical methods are very hard to achieve. The aim of this note is to point out a new connection… 

The Calder\'on problem with finitely many unknowns is equivalent to convex semidefinite optimization

We consider the inverse boundary value problem of determining a coefficient function in an elliptic partial differential equation from knowledge of the associated Neumann-Dirichlet-operator. The unknown

This text shows how to efficiently implement both using a standard FEM package and prove convergence of the FEM approximations against their true-solution counterparts, and numerically demonstrates the challenges that arise from non-uniqueness, non-linearity and instability issues.

Uniqueness, stability and global convergence for a discrete inverse elliptic Robin transmission problem

It is shown that a piecewise-constant coefficient on an a-priori known partition with a-Priori known bounds is uniquely determined by finitely many boundary measurements and that it can be uniquely and stably reconstructed by a globally convergent Newton iteration.

Uniqueness and Lipschitz stability in electrical impedance tomography with finitely many electrodes

For the linearized reconstruction problem in electrical impedance tomography with the complete electrode model, Lechleiter and Rieder (2008 Inverse Problems 24 065009) have shown that a piecewise

Convexification of electrical impedance tomography with restricted Dirichlet-to-Neumann map data

We propose a new numerical method to reconstruct the isotropic electrical conductivity from measured restricted Dirichlet-to-Neumann map data in electrical impedance tomography (EIT). ‘Restricted

Calderón's inverse problem with a finite number of measurements II: independent data

ABSTRACT We prove a local Lipschitz stability estimate for Gel'fand-Calderón's inverse problem for the Schrödinger equation. The main novelty is that only a finite number of boundary input data is

Lipschitz stability for the finite dimensional fractional Calderón problem with finite Cauchy data

In this note we discuss the conditional stability issue for the finite dimensional Calder\'on problem for the fractional Schr\"{o}dinger equation with a finite number of measurements. More precisely,

On uniqueness in diffuse optical tomography

A prominent result of Arridge and Lionheart (1998 Opt. Lett. 23 882–4) demonstrates that it is in general not possible to simultaneously recover both the diffusion (aka scattering) and the absorption

Stable Determination of Polyhedral Interfaces from Boundary Data for the Helmholtz Equation

We study an inverse boundary value problem for the Helmholtz equation using the Dirichlet-to-Neumann map. We consider piecewise constant wave speeds on an unknown tetrahedral partition and prove a

Electrical impedance tomography and Calderón's problem

We survey mathematical developments in the inverse method of electrical impedance tomography which consists in determining the electrical properties of a medium by making voltage and current
