Abstract
Let (F_1, \ldots , F_n): \mathbb {C}^n \to \mathbb {C}^{n} be a locally invertible polynomial map. We consider the canonical pull-back vector fields under this map, denoted by \partial / \partial F_1, \ldots , \partial / \partial F_n . Our main result is the following: if n-1 of the vector fields \partial / \partial F_j have complete holomorphic flows along the typical fibers of the submersion (F_1, \ldots , F_{j -1}, F_{j+1} , \ldots , F_n), then the inverse map exists. Several equivalent versions of this main hypothesis are given.
