Fourier Transform,ned on the Banach space .. The main properties of the Fourier transform are handled, such as the Fourier inversion formula and the convolution property. Then, in Sect. 2.2, the Fourier transform is introduced as a bijective mapping of the Hilbert space . onto itself by the theorem of Plancherel. The
