WebThe Paley Wiener Theorems in Rn The relationship of the growth of an entire function with the properties of its Fourier transform are embodied in the well known Paley-Wiener theorems. For functions of complex vari-able, we have: Theorem 1 (PW1). A function f :C→C is an entire function of exponential type with its restriction f R ∈L 2(R) iff ... WebAs noted in the last section, as a corollary of the Paley-Wiener theorem for test functions, Fourier transforms of arbitrary distributions exist, and lie in the dual of the Paley-Wiener …

WebFeb 14, 2024 · In fact, from Delorme's Paley-Wiener theorem for compactly supported smooth functions on a real reductive group of Harish-Chandra class, we deduce … In mathematics, a Paley–Wiener theorem is any theorem that relates decay properties of a function or distribution at infinity with analyticity of its Fourier transform. The theorem is named for Raymond Paley (1907–1933) and Norbert Wiener (1894–1964). The original theorems did not use the … See more The classical Paley–Wiener theorems make use of the holomorphic Fourier transform on classes of square-integrable functions supported on the real line. Formally, the idea is to take the integral defining the … See more Schwartz's Paley–Wiener theorem asserts that the Fourier transform of a distribution of compact support on R is an entire function on C and gives estimates on its growth at infinity.
