Bulletin de la Société Mathématique de France, Tome 129 (2001) no. 1, pp. 33-90.

On montre que certaines des fonctions $L$ de $\mathrm{Gl}\left(2\right)$ obtenues par changement de base quadratique sont positives en leur centre de symétrie.

We show that certain quadratic base change $L$-functions for $\mathrm{Gl}\left(2\right)$ are non-negative at their center of symmetry.
