Invariant metrics and peak functions on pseudoconvex domains of homogeneous finite diagonal type.
Following Sibony, we say that a bounded domain in is -regular if every continuous real valued function on the boundary of can be extended continuously to a plurisubharmonic function on . The aim of this paper is to study an analogue of this concept in the category of unbounded domains in . The use of Jensen measures relative to classes of plurisubharmonic functions plays a key role in our work
Soit un fibré holomorphe localement trivial de base une variété de Stein et de fibre une courbe compacte.Si est un ouvert localement pseudoconvexe de ne contenant aucune fibre, alors est de Stein.
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...
