# Mellin transforms


“An integral transform with scale invariance like the Fourier transform has shift invariance”. From my perspective, useful for analysing multiplicative products of random variables, their reciprocal and powers, much as the Fourier transform is useful for sums of scaled random variables.

For now, see the Mellin transform on Wikipedia.

Approachable references seem to be Bertrand, Bertrand, and Ovarlez (2000); Flajolet, Gourdon, and Dumas (1995); Galambos and Simonelli (2004).
