Infinite-dimensional Lipschitz stability in the Calderón problem and general Zernike bases
Henrik Garde, Markus Hirvensalo, Nuutti Hyvönen
Calderón's inverse conductivity problem has, so far, only been subject to conditional logarithmic stability for infinite-dimensional classes of conductivities and to Lipschitz stab…
Construction of invisible conductivity perturbations for the point electrode model in electrical impedance tomography
Lucas Chesnel, Nuutti Hyvönen, Stratos Staboulis
We explain how to build invisible isotropic conductivity perturbations of the unit conductivity in the framework of the point electrode model for two-dimensional electrical impedan…
Point measurements for a Neumann-to-Dirichlet map and the Calderón problem in the plane
Nuutti Hyvönen, Petteri Piiroinen, Otto Seiskari
This work considers properties of the Neumann-to-Dirichlet map for the conductivity equation under the assumption that the conductivity is identically one close to the boundary of…
