Wave fronts via Fourier series coefficients

Snjezana Maksimovic, Stevan Pilipovic, Petar Sokoloski +1

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 $f\in {\mathcal{D}}^{\prime }({\mathbb{R}}^d)$ i…
