WebJul 9, 2024 · Linearity: For any functions f(x) and g(x) for which the Fourier transform exists and constant a, we have F[f + g] = F[f] + F[g] and F[af] = aF[f]. These simply follow from the properties of integration and establish the linearity of the Fourier transform. Transform of a Derivative: F[df dx] = − ikˆf(k)

When trying to find the Fourier transform of the Coulomb potential. V ( r) = − e 2 r. one is faced with the problem that the resulting integral is divergent. Usually, it is then argued to introduce a screening factor e − μ r and take the limit lim μ → 0 at the end of the calculation. This always seemed somewhat ad hoc to me, and I ...
