On vector-valued Hörmander-Beurling spaces.
The weighted inductive limit of Fréchet spaces of entire functions in N variables which is obtained as the Fourier-Laplace transform of the space of analytic functionals on an open convex subset of can be described algebraically as the intersection of a family of weighted Banach spaces of entire functions. The corresponding result for the spaces of quasianalytic functionals is also derived.
We introduce pseudodifferential operators (of infinite order) in the framework of non-quasianalytic classes of Beurling type. We prove that such an operator with (distributional) kernel in a given Beurling class is pseudo-local and can be locally decomposed, modulo a smoothing operator, as the composition of a pseudodifferential operator of finite order and an ultradifferential operator with constant coefficients in the sense of Komatsu, both operators with kernel in the same class . We also...
Deux décompositions d’une fonctionnelle d’un espace d’ultra-distributions sont étudiées. La première fait intervenir une série convergente de dérivées de mesures dont on montre que les supports peuvent être pris inclus dans le support . La seconde consiste à exprimer comme somme de fonctionnelles du même espace portées par les éléments d’une partition du support de . Dans les deux cas on a recours à des concepts de régularité et de séparation régulière d’ensembles fermés de qui relient la...
nbspAbstract. We give the definition of regular distributions and some characterizations of absolutely regular and regular -distributions.
