SEMINAR: Uncertainty principles for Fourier transform
Guest: Sergey Tikhonov, Centre de Recerca Matemàtica (CRM) in Barcelona
Title: Uncertainty principles
Date/Time: February 25, 2026, 12:40
Location: FENS G032
Abstract: The uncertainty principles forbid a function and its Fourier transform from simultaneously being too (or critically) localized. We discuss several well-known and new Fourier uncertainty principles including those by Hardy and Cowling-Price principle. The talk is intended for a general audience, no specialized background knowledge is required.
Joint work with Miquel Saucedo.
