Dolićanin-Djekić, Dijana; Maksimović, Snjezana; Sokoloski, Petaar Wave fronts of ultradistributions via Fourier series coefficients. (English) Zbl 1353.35012 Mat. Bilt. 39, No. 2, 53-59 (2015). Summary: We shall use the properties of the product of periodic ultradistributions and give a new description of the wave front of an ultradistribution \(f\in \mathcal{D}^{\ast\prime}(\mathbb{R}^d)\) in terms of Fourier series coefficients.
