Résumé
Abstract

On montre que pour toute solution de $SU (3)$ système de Toda suivant $Δ u + 2 e^{u} - e^{v} = 0$ , $Δ v - e^{u} + 2 e^{v} = 0$ dans $R^{2}$ , $\int_{R^{2}} e^{u} < \infty$ , $\int_{R^{2}} e^{v} < \infty$ , le noyau de l'opérateur linéarisé associé est exactement de dimension huit, i.e., ce qu'on appelle la nondégénérescence.

We prove that the solution to the following $SU (3)$ Toda system

{\begin{matrix} Δ u + 2 e^{u} - e^{v} = 0, Δ v - e^{u} + 2 e^{v} = 0 in R^{2}, \\ \int_{R^{2}} e^{u} < \infty, \int_{R^{2}} e^{v} < \infty, \end{matrix}

is nondegenerate, i.e., the kernel of the associated linearized operator is exactly eight-dimensional.
