Wave fronts via Fourier series coefficients
Published 15 Jul 2014 in math.AP and math.FA | (1407.4155v2)
Abstract: Motivated by the product of periodic distributions, we give a new description of the wave front and the Sobolev-type wave front of a distribution $f\in\mathscr{D}'(\mathbb{R}d)$ in terms of Fourier series coefficients.
