WebJun 16, 2024 · Yes, you can get uniqueness for the Fourier transform from uniqueness for Fourier series, by a Poisson-summation sort of argument. But it's very simple to do directly. Note I'm omitting the 2 π s: Lemma. If f, g ∈ L 1 ( R) then ∫ f ^ g = ∫ f g ^. Proof. Fubini. Prop. If f ∈ L 1 and f ^ = 0 then f = 0 a.e. http://export.arxiv.org/abs/2208.12219
