Ultraholomorphic extension theorems in the mixed setting [PDF]

open access: yes, 2019
The aim of this work is to generalize the ultraholomorphic extension theorems from V. Thilliez in the weight sequence setting and from the authors in the weight function setting (of Roumieu type) to a mixed framework. Such mixed results have already been

Convolution equations for ultradifferentiable functions and ultradistributions

open access: yesJournal of Mathematical Analysis and Applications, 2004
For convolution operators acting on spaces of ultradistributions of Beurling type on open sets, the authors characterize the surjectivity of the operator (modulo ultrasmooth functions) in terms of a convexity condition for singular supports in the spirit of Hörmander's convexity conditions (Theorem A).

On invertibility of Duhamel operator in spaces of ultradifferentiable functions

open access: yesUfa Mathematical Journal, 2023
Summary: Let \(\Delta\) be a non-point segment or an (open) interval on the real line containing the point 0. In the space of entire functions realized by the Fourier-Laplace transform of the dual space to the space of ultradifferentiable or of all infinitely differentiable functions on \(\Delta \), we study the operators from the commutator subgroup ...

Smooth solutions of quasianalytic or ultraholomorphic equations [PDF]

open access: yes, 2010
8 pagesInternational audienceIn the first part of this work, we consider a polynomial $ \phi(x,y)=y^d+a_1(x)y^{d-1}+...+a_d(x) $ whose coefficients $ a_j $ belong to a Denjoy-Carleman quasianalytic local ring $ \mathcal{E}_1(M) $.

Indices of O-regular variation for weight functions and weight sequences [PDF]

open access: yes, 2018
A plethora of spaces in Functional Analysis (Braun-Meise-Taylor and Carleman ultradifferentiable and ultraholomorphic classes; Orlicz, Besov, Lipschitz, Lebesque spaces, to cite the main ones) are defined by means of a weighted structure, obtained from a

Whitney’s extension theorem for ultradifferentiable functions of Beurling type

open access: yesArkiv för Matematik, 1988
The authors introduce classes of non-quasianalytic functions \({\mathcal E}_{\omega}({\mathbb{R}}^ n)\) similar to those treated by Beurling and Björck: Given a weight function \(\omega\) : \({\mathbb{R}}\to [0,\infty [\) (i.e. \(\omega\) is continuous, even, increasing on [0,\(\infty [\), satisfies \(\omega (0)=0\), lim \(\omega\) (t)\(=\infty ...

Convolution of ultradistributions and ultradistribution spaces associated to translation-invariant Banach spaces [PDF]

open access: yes, 2016
We introduce and study a number of new spaces of ultradifferentiable functions and ultradistributions and we apply our results to the study of the convolution of ultradistributions. The spaces of convolutors O-C'*(R-d) for tempered ultradistributions are
