Existence and regularity of solutions of the δ ¯ -system on wedges of C N

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

For a wedge W of C N , we introduce two conditions of weak q -pseudoconvexity, and prove that they entail solvability of the δ ¯ -system for forms of degree q + 1 with coefficients in C W and C W ¯ respectively. Existence and regularity for δ ¯ in W is treated by Hörmander [5, 6] (and also by Zampieri [9, 11] in case of piecewise smooth boundaries). Regularity in W is treated by Henkin [4] (strong q -pseudoconvexity by the method of the integral representation), Dufresnoy [3] (full pseudoconvexity), Michel [8] (constant...

Extension dans des classes de Hardy de fonctions holomorphes et estimations de type «mesures de Carleson» pour l’équation ¯

Anne Cumenge (1983)

Annales de l'institut Fourier

Nous montrons qu’une fonction holomorphe sur un sous-ensemble analytique transverse V d’un domaine D borné strictement pseudoconvexe de C n admet une extension dans H p ( D ) ( 1 p < + ) si et seulement si elle vérifie une condition de type L p à poids sur V  ; la démonstration est en partie basée sur la résolution de l’équation avec estimations de type “mesures de Carleson”.

Extension of CR functions to «wedge type» domains

Let X be a complex manifold, S a generic submanifold of X R , the real underlying manifold to X . Let Ω be an open subset of S with Ω analytic, Y a complexification of S . We first recall the notion of Ω -tuboid of X and of Y and then give a relation between; we then give the corresponding result in terms of microfunctions at the boundary. We relate the regularity at the boundary for ¯ b to the extendability of C R functions on Ω to Ω -tuboids of X . Next, if X has complex dimension 2, we give results on extension...

Finitely generated ideals in A ( ω )

Annales de l'institut Fourier

The Gleason problem is solved on real analytic pseudoconvex domains in C 2 . In this case the weakly pseudoconvex points can be a two-dimensional subset of the boundary. To reduce the Gleason problem to a question it is shown that the set of Kohn-Nirenberg points is at most one-dimensional. In fact, except for a one-dimensional subset, the weakly pseudoconvex boundary points are R -points as studied by Range and therefore allow local sup-norm estimates for .
