On Krylov solutions to infinite-dimensional inverse linear problems (1811.08202v2)
Published 20 Nov 2018 in math.NA, cs.NA, and math.FA
Abstract: We discuss, in the context of inverse linear problems in Hilbert space, the notion of the associated infinite-dimensional Krylov subspace and we produce necessary and sufficient conditions for the Krylov-solvability of a given inverse problem, together with a series of model examples and numerical experiments.
