Stability estimates for reconstruction from the Fourier transform on the ball

Classical Analysis and ODEs 2020-07-24 v1

Abstract

We prove H\"{o}lder-logarithmic stability estimates for the problem of finding an integrable function vv on Rd\mathbb{R}^d with a super-exponential decay at infinity from its Fourier transform Fv\mathcal{F} v given on the ball BrB_r. These estimates arise from a H\"{o}lder-stable extrapolation of Fv\mathcal{F} v from BrB_r to a larger ball. We also present instability examples showing an optimality of our results.
