Catalogue Note
La résolution algébrique des équations
Important ouvrage à l'origine de la théorie des groupes et de l'algèbre moderne. La première édition remonte à 1798. Lagrange donne la méthode d'approximation de la véritable racine d'une équation numérique par des fractions continues, ainsi que la preuve que toute équation doit avoir une racine.
