Optimal stability of regularized spectral differentiation in Sobolev spaces

Teemu Tyni

We study the problem of stable spectral differentiation of functions in Sobolev spaces from noisy data. We introduce a class of admissible Fourier multipliers under simple and dire…

Optimal recovery of a radiating source with multiple frequencies along one line

Tommi Brander, Joonas Ilmavirta, Petteri Piiroinen +1

We study an inverse problem where an unknown radiating source is observed with collimated detectors along a single line and the medium has a known attenuation. The research is moti…
