[Estimes sommes–produits et sur les sommes exponentielles associées à des sous-groupes d'un corps d'ordre premier]
Notre premier résultat est un théorème « sommes–produits » pour des sous-ensembles A d'un corps fini , p un nombre premier, donnant une minoration du max(|A+A|,|A·A|). Comme corollaire et résultat principal, on en déduit de nouvelles bornes sur les sommes exponentielles associées à des sous-groupes du groupe multiplicatif .
Our first result is a ‘sum–product’ theorem for subsets A of the finite field , p prime, providing a lower bound on max(|A+A|,|A·A|). As corollary, the second and main result provides new bounds on exponential sums associated to subgroups of the multiplicative group .
