Universal completeness of exponentials

Susanna Bertolini, Enric Florit-Simon, Lukas Liehr +1

We consider generalizations of the classical Fourier uniqueness theorem. First, we construct a family of uniformly discrete sets $Λ \subset R$ , of uniform density one, such…

$L^{2}$ -Stability for STFT phase retrieval

Susanna Bertolini, Jaume de Dios Pont, Ben Pineau +2

We prove that the short-time Fourier transform with Gaussian window performs $L^{2}$ -local stable phase retrieval at the constant function. The proof involved significant interplay b…
