Iteration theory, compactly divergent sequences and commuting holomorphic maps
We characterise hyperconvexity in terms of Jensen measures with barycentre at a boundary point. We also give an explicit formula for the pluricomplex Green function in the Hartogs triangle. Finally, we study the behaviour of the pluricomplex Green function g(z,w) as the pole w tends to a boundary point.
A Coburn theorem says that a nonzero Toeplitz operator on the Hardy space is one-to-one or its adjoint operator is one-to-one. We study the corresponding problem for certain Toeplitz operators on the Bergman space.
We give a characterization of -domains of holomorphy with the help of the boundary behavior of the Bergman kernel and geometric properties of the boundary, respectively.
On donne des évaluations précises de la croissance modérée des intégrales de fonctions de classe de Nilsson locale dans , exprimées par des caractéristiques topologiques des courbes de ramification des intégrands.
We prove, among other results, that is plurisubharmonic (psh) when belong to a family of functions in where is the -Lipchitz functional space with Then we establish a new characterization of holomorphic functions defined on open sets of
Étude de la possibilité d’inverser le théorème de Bremerman : si et sont deux domaines bornés dans et et si , alors où désigne la fonction-noyau de Bergman. On introduit une classe de domaines dans qui contient les domaines de Reinhardt et de Hartogs et différentes fonctions “correctives” qui expriment la différence entre la fonction-noyau du domaine et le produit des fonctions-noyaux de sa “base” dans et de ses “fibres” dans . Divers moyens d’inverser le théorème de Bremerman...
In 1984 L. Lempert showed that the Lempert function and the Carathéodory distance coincide on non-planar bounded strongly linearly convex domains with real-analytic boundaries. Following his paper, we present a slightly modified and more detailed version of the proof. Moreover, the Lempert Theorem is proved for non-planar bounded strongly linearly convex domains.
Let G be a complex semi-simple group with a compact maximal group K and an irreducible holomorphic representation ρ on a finite dimensional space V. There exists on V a K-invariant Hermitian scalar product. Let Ω be the intersection of the unit ball of V with the G-orbit of a dominant vector. Ω is a generalization of the unit ball (case obtained for G = SL(n,C) and ρ the natural representation on Cn).We prove that for such manifolds, the Bergman and Szegö kernels as for the ball are rational fractions...
