A theorem concerning Fourier transforms: A survey

Abstract In this note, we highlight the impact of the paper G. H. Hardy, A theorem concerning Fourier transforms , J. Lond. Math. Soc. (1) 8 (1933), 227–231 in the community of harmonic analysis in the last 90 years, reviewing, on one hand, the direct generalizations of the main results and, on the other hand, the different connections to related areas and new perspectives.
