ملخص: Dans cette Note on etudie les conditions pour qu'un systeme d'equations differentielles ordinaires possede une superposition des solutions, et egalement la linearisation de tels systemes. On etudie plus particulierement l'equation de Riccati. Pour citer cet article : S. Rezzag et al., C. R. Acad. Sci. Paris, Ser. I 340 (2005).AbstractIn this Note we study the conditions under which a system of ordinary differential equations admits a nonlinear superposition of the solutions, and also the linearization of such systems. A particular study is established for the Riccati equation. To cite this article: S. Rezzag et al., C. R. Acad. Sci. Paris, Ser. I 340 (2005).
