A Ritz method for solution of parametric generalized EVPs
Joanna Bisch, Antti Hannukainen
This work deals with approximate solution of generalized eigenvalue problem with coefficient matrix that is an affine function of d-parameters. The coefficient matrix is assumed to…

Continuity of the linearized forward map of electrical impedance tomography from square-integrable perturbations to Hilbert-Schmidt operators
Joanna Bisch, Markus Hirvensalo, Nuutti Hyvönen
This work considers the Fréchet derivative of the idealized forward map of two-dimensional electrical impedance tomography, i.e., the linear operator that maps a perturbation of th…

On the rational approximation of Markov functions,with applications to the computation of Markovfunctions of Toeplitz matrices
Bernhard Beckermann, Joanna Bisch, Robert Luce
We investigate the problem of approximating the matrix function by , with a Markov function, a rational interpolant of , and a symmetric Toeplitz matrix…
