fourier transform - What is a wavenumber? - Mathematics Stack Exchange Is a wavenumber we talk about in the context of wave propagation in physics (say ocean waves, or acoustics) same as wavenumber as in Fourier Transform? What is horizontal Fourier transform? What is the meaning of a vertical wavenumber if a wave doesn't travel out radially from an origin as a sphere
What is Fourier Space - Mathematics Stack Exchange I know a some basics stuff regarding Fourier Analysis (Fourier series and Fourier transforms), but I've seen the term " Fourier Space " come up and I'm having trouble finding a definition for what this is
Properties of Riesz transform - Mathematics Stack Exchange The first Fourier transform above can be found in this well-written expository paper The second is similarly "well-known" and can be found in e g Stein's book "Singular Integrals and Differentiability Properties of Functions", or for instance, this PDF file
