Quotients jacobiens d'applications polynomiales
[Jacobian quotients of polynomial mappings]
Annales de l'Institut Fourier, Volume 53 (2003) no. 2, pp. 399-428.

Let $\phi :=\left(f,g\right):{ℂ}^{2}\to {ℂ}^{2}$ where $f$ and $g$ are polynomial maps. A relationship is established between the following two objects: on the one hand, the Newton polygon of the union of the discriminant curve of $\phi$ and its non-properness locus, and on the other, the topological type of the link at infinity of the affine curves ${f}^{-1}\left(0\right)$ and ${g}^{-1}\left(0\right)$. Some consequences related to the Jacobian Conjecture are obtained.

Soit $\phi :=\left(f,g\right):{ℂ}^{2}\to {ℂ}^{2}$$f$ et $g$ sont des applications polynomiales. Nous établissons le lien qui existe entre le polygone de Newton de la courbe réunion du discriminant et du lieu de non-propreté de $\phi$ et la topologie des entrelacs à l’infini des courbes affines ${f}^{-1}\left(0\right)$ et ${g}^{-1}\left(0\right)$. Nous en déduisons alors des conséquences liées à la conjecture du jacobien.
