Gaussian transforms
WebHence, you got three Fourier transform of a Gaussian. A Fourier transform of each Gaussian is given by: ∫ − ∞ ∞ e − i r q − a 2 r 2 d r = π a e − q 2 4 a. So your integral all in all is equal to a product of those three Gaussians in ( q 1, q 2, q 3). Assuming I didn't make any mistake along the way: WebJun 5, 2024 · The above inversion formula can be interpreted in terms of semi-groups. Another way to invert the Gauss transform is to write in the first equation $ t + u = v $, …
