APDE Seminar @BCAM: Phase retrieval and Fourier uniqueness problems

Abstract 

A phase retrieval problem consists of recovering the phase of a function with the knowledge of physical measurements. Pauli studied this problem when the measurements are the absolute value of the function and its Fourier transform, and we are gonna discuss what can be said when one samples the absolute value of a function and its Fourier transform over discrete sets. This talk is based on joint work with João Pedro Ramos (University of Lisbon).
