A novel definition of real Fourier transform

General Mathematics 2025-02-26 v1

Abstract

We propose a novel definition of Fourier transform, with the property that the transform of a real function is again a real function (without doubling the number of real components). We prove the inversion theorem for the novel definition, and show that it shares the good properties of the usual definition.
