Green functions with analytic singularities
[Fonctions de Green avec singularités analytiques]
Comptes Rendus. Mathématique, Volume 340 (2005) no. 7, pp. 479-482.

Nous étudions des propriétés d'une fonction de Green avec des singularités determinées par un sous-espace fermé complexe A d'une variété complexe lisse X. Elle est définie comme la plus grande fonction plurisouharmonique u négative vérifiant ulog|ψ|+O(1), où ψ=(ψ1,,ψm) avec ψ1,,ψm générateurs locaux du faisceau d'idéaux IA de A.

We study properties of a Green function with singularities determined by a closed complex subspace A of a complex manifold X. It is defined as the largest negative plurisubharmonic function u satisfying locally ulog|ψ|+O(1), where ψ=(ψ1,,ψm) with ψ1,,ψm local generators for the ideal sheaf IA of A.
