Formules explicites pour les solutions minimales de l’équation ¯ u = f dans la boule et dans le polydisque de n

Philippe Charpentier (1980)

Annales de l'institut Fourier

Dans cet article, on construit tout d’abord un noyau de Cauchy explicite dans la boule unité B de C n dont les valeurs au bord sont égales au noyau de Szegö. Puis, à partir de ce noyau, on construit explicitement les noyaux qui fournissent les solutions de l’équation u = f qui sont orthogonales aux fonctions holomorphes dans les espaces L 2 ( d σ α ) , où d σ α ( z ) = ( 1 - | z | 2 ) d λ ( z ) , d λ ( z ) étant la mesure de Lebesgue et α un réel > - 1 . Nous donnons ensuite les principales estimations dedans et au bord que vérifient ces solutions. Dans une deuxième...

Generically strongly q -convex complex manifolds

Terrence Napier, Mohan Ramachandran (2001)

Annales de l’institut Fourier

Suppose ϕ is a real analytic plurisubharmonic exhaustion function on a connected noncompact complex manifold X . The main result is that if the real analytic set of points at which ϕ is not strongly q -convex is of dimension at most 2 q + 1 , then almost every sufficiently large sublevel of ϕ is strongly q -convex as a complex manifold. For X of dimension 2 , this is a special case of a theorem of Diederich and Ohsawa. A version for ϕ real analytic with corners is also obtained.

Grauert's line bundle convexity, reduction and Riemann domains

Viorel Vâjâitu (2016)

Czechoslovak Mathematical Journal

We consider a convexity notion for complex spaces X with respect to a holomorphic line bundle L over X . This definition has been introduced by Grauert and, when L is analytically trivial, we recover the standard holomorphic convexity. In this circle of ideas, we prove the counterpart of the classical Remmert’s reduction result for holomorphically convex spaces. In the same vein, we show that if H 0 ( X , L ) separates each point of X , then X can be realized as a Riemann domain over the complex projective space...
