Résumé
Abstract

Un système lent–rapide de type $A_{k}$ est une équation différentielle ordinaire singulièrement perturbée avec une structure particulière. La varieté lente correspondante est définie par les points critiques d'un déploiment universel d'une singularité de type $A_{k}$ . Dans cette note, nous proposons une forme normale formelle des systèmes lents–rapides de type $A_{k}$ .

An $A_{k}$ slow–fast system is a particular type of singularly perturbed ODE. The corresponding slow manifold is defined by the critical points of a universal unfolding of an $A_{k}$ singularity. In this note we propose a formal normal form of $A_{k}$ slow–fast systems.
