Finite element approximation of source term identification with TV-regularization
Michael Hinze, Tran Nhan Tam Quyen
In this paper we investigate the problem of recovering the source term in an elliptic system from a measurement of the state on a part of the boundary. For the particular interest…
A reaction coefficient identification problem for fractional diffusion
Enrique Otarola, Tran Nhan Tam Quyen
We analyze a reaction coefficient identification problem for the spectral fractional powers of a symmetric, coercive, linear, elliptic, second-order operator in a bounded domain $Ω…
Identifying conductivity in electrical impedance tomography with total variation regularization
Michael Hinze, Barbara Kaltenbacher, Tran Nhan Tam Quyen
In this paper we investigate the problem of identifying conductivity in electrical impedance tomography from one boundary measurement. A variational method with total variation reg…
Matrix Coefficient Identification in an Elliptic Equation with the Convex Energy Functional Method
Michael Hinze, Tran Nhan Tam Quyen
In this paper we study the inverse problem of identifying the diffusion matrix in an elliptic PDE from measurements. The convex energy functional method with Tikhonov regularizatio…
