It is known that the existence of a holomorphic tubular neighborhood of a compact submanifold of a compact complex manifold is rare; for example, the classical theorem due to Van de Ven states that the only submanifolds of CP(n) that possess a holomorphic tubular neighborhood are the linear ones. However, when X is a meromorphic vector field in a neighborhood of a submanifold S such that the assoc
