Oversampling and undersampling in de Branges spaces arising from regular Schrödinger operators

arXiv:1804.05888 · doi:10.1007/s11785-018-0853-y

Abstract

The classical results on oversampling and undersampling (or aliasing), of functions in Paley-Wiener spaces, are generalized to the case of functions in de Branges spaces arising from regular Schrödinger operators with a wide range of potentials.
