Some remarks on convolution equations
Annales de l'Institut Fourier, Tome 23 (1973) no. 1, pp. 55-73.

Par voie d’une description de la topologie des espaces E (Ω) (Ω ouvert convexe dans R n ) via la transformation de Fourier, c’est-à-dire leurs structures analytiques uniformes, on arrive à une formule qui décrit l’enveloppe convexe du support singulier d’une distribution T, TE . On donne des applications à une classe des distributions qui satisfont à l’égalité

cv. sing. supp. S * T = cv. sing. supp. S + cv. sing. supp. T

pour toutes SE .

Using a description of the topology of the spaces E (Ω) (Ω open convex subset of R n ) via the Fourier transform, namely their analytically uniform structures, we arrive at a formula describing the convex hull of the singular support of a distribution T, TE . We give applications to a class of distributions T satisfying

cv. sing. supp. S * T = cv. sing. supp. S + cv. sing. supp. T

for all SE .
