Discrete approximations to Dirichlet and Neumann Laplacians on a half-space and norm resolvent convergence
Horia Cornean, Henrik Garde, Arne Jensen
We extend recent results on discrete approximations of the Laplacian in with norm resolvent convergence to the corresponding results for Dirichlet and Neumann Laplac…
Series reversion for electrical impedance tomography with modeling errors
Henrik Garde, Nuutti Hyvönen, Topi Kuutela
This work extends the results of [Garde and Hyvönen, Math. Comp. 91:1925-1953] on series reversion for Calderón's problem to the case of realistic electrode measurements, with both…
Linearised Calderón problem: Reconstruction and Lipschitz stability for infinite-dimensional spaces of unbounded perturbations
Henrik Garde, Nuutti Hyvönen
We investigate a linearised Calderón problem in a two-dimensional bounded simply connected domain . After extending the linearised problem for perturbations,…
Discrete approximations to Dirac operators and norm resolvent convergence
Horia D. Cornean, Henrik Garde, Arne Jensen
We consider continuous Dirac operators defined on , , together with various discrete versions of them. Both forward-backward and symmetric finite diffe…
