(I'm reposting this from math.stackexchange as I didn't get an answer there and thought it might be "advanced" enough for this site.) As one may know, the Fourier Transform $$F[f](\nu) = ...
In the paper "A Convolution Inequality Concerning Cantor-Lebesgue Measures", the Littlewood-Paley theory is used to estimate the norm of multiplier operator in Lemma 1. It is claimed that Lemma 2 is ...
In solving a linear system, when would I use a Fourier transform versus a Laplace transform? I am not a mathematician, so the little intuition I have tells me that it could be related to the boundary ...
