[Déformations des schémas localement intersections complètes]
Given a projective l.c.i. scheme, , we show that X has a smooth formal neighbourhood in which X is globally a complete intersection; that is, X is the intersection of codim(X) hypersurfaces.
Soit X un schéma projectif et localement intersection complète. On démontre qu'il existe un voisinage formel, X∞, de X, dans lequel X est une intersection complète globale ; c'est-à-dire que X est l'intersection de codim(X) hypersurfaces.
