Abstract
Résumé

The purpose of this survey is to provide the reader with a user friendly introduction to the two articles [8] and [9], which give a Galoisian description of the action of an endomorphism of a differential field $(K, \partial)$ on the solutions of a linear differential equation defined over $(K, \partial)$ . After having introduced the theory, we give some concrete examples.

Le but de ce survol est de présenter d’une façon accessible le contenu des articles [8] et [9], qui donnent une description galoisienne de l’action d’un endomorphisme d’un corps différentiel $(K, \partial)$ sur les solutions d’une équation différentielle linéaire à coefficients dans $(K, \partial)$ . Après une présentation de la théorie nous donnons quelques exemples d’applications.
