The Calderón problem with corrupted data
Caro, P.; García, A. (201701)We consider the inverse Calderón problem consisting of determining the conductivity inside a medium by electrical measurements on its surface. Ideally, these measurements determine the DirichlettoNeumann map and, therefore, ... 
Correlation imaging in inverse scattering is tomography on probability distributions
Caro, P.; Helin, T.; Kujanpää, A.; Lassas, M. (20181204)Scattering from a nonsmooth random field on the time domain is studied for plane waves that propagate simultaneously through the potential in variable angles. We first derive sufficient conditions for stochastic moments ... 
Determination of convection terms and quasilinearities appearing in diffusion equations
Caro, P.; Kian, Y. (201812)We consider the highly nonlinear and ill posed inverse problem of determining some general expression appearing in the a diffusion equation from measurements of solutions on the lateral boundary. We consider both linear ... 
Global Uniqueness for The Calderón Problem with Lipschitz Conductivities
Caro, P.; Rogers, K.M. (20160101)We prove uniqueness for the Calderón problem with Lipschitz conductivities in higher dimensions. Combined with the recent work of Haberman, who treated the three and fourdimensional cases, this confirms a conjecture of ... 
Inverse scattering for a random potential
Caro, P.; Helin, T.; Lassas, M. (201605)In this paper we consider an inverse problem for the $n$dimensional random Schrödinger equation $(\Deltaq+k^2)u = 0$. We study the scattering of plane waves in the presence of a potential $q$ which is assumed to be a ... 
The observational limit of wave packets with noisy measurements
Caro, P.; Meroño, C. (2019)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 random errors are generated by a Gaussian ... 
Rotational smoothing
Caro, P.; Meroño, C.; Parissis, I. (20220105)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 certain directions, in contrast to operators ... 
Scattering with criticallysingular and δshell potentials
Caro, P.; García, A. (2019)The authors consider a scattering problem for electric potentials that have a component which is critically singular in the sense of Lebesgue spaces, and a component given by a measure supported on a compact Lipschitz ... 
Unique determination of the electric potential in the presence of a fixed magnetic potential in the plane
Caro, P.; Rogers, K. (201812)For electric and magnetic potentials with compact support, we consider the magnetic Schrödinger equation with fixed positive energy. Under a mild additional regularity hypothesis, and with fixed magnetic potential, we show ...
