Extending holomorphic mappings from subvarieties in Stein manifolds
[Prolongements holomorphes dans les variétés de Stein]
Annales de l'Institut Fourier, Tome 55 (2005) no. 3, pp. 733-751.

Soit Y une variété analytique complexe telle que toute application holomorphe d’une partie convexe compacte de l’espace euclidien n à valeurs dans Y est limite uniforme d’applications entières à valeurs dans Y. On prouve que toute application holomorphe d’un sous ensemble analytique complexe fermé X 0 d’une variété de Stein X à valeurs dans Y possède un prolongement holomorphe à X à condition qu’elle admette un prolongement continu. On établit ensuite l’équivalence entre quatre propriétés de type Oka pour une variété analytique complexe.

Suppose that Y is a complex manifold such that any holomorphic map from a compact convex set in a Euclidean space n to Y is a uniform limit of entire maps n Y. We prove that a holomorphic map X 0 Y from a closed complex subvariety X 0 in a Stein manifold X admits a holomorphic extension XY provided that it admits a continuous extension. We then establish the equivalence of four Oka-type properties of a complex manifold.
