e/Riesz transform

Information
has gloss	eng: In the mathematical theory of harmonic analysis, the Riesz transforms are a family of generalizations of the Hilbert transform to Euclidean spaces of dimension d > 1. They are a type of singular integral operator, meaning that they are given by a convolution of one function with another function having a singularity at the origin. Specifically, the Riesz transforms of a complex-valued function ƒ on Rd are defined by \,dt\|}} for j = 1,2,...,d. The constant cd is a dimensional normalization given by
