Résumé
Abstract

Soit p un nombre premier suffisamment grand et ${(L_{i})}_{1 ⩽ i ⩽ n}$ un système non-dégénéré de formes linéaires sur $F_{p}$ en n variables. Nous obtenons une estimée non-triviale de la somme incomplète

\sum_{x \in \prod_{i = 1}^{n} [a_{i}, a_{i} + H]} X (\prod_{j = 1}^{n} L_{j} (x)),

où

X \neq 1

est un caractère multiplicatif

(\mod p)

et

H > p^{\frac{1}{4} + ε}

.

Let p be a sufficiently large prime and ${(L_{i})}_{1 ⩽ i ⩽ n}$ a nondegenerate system of linear forms in n variables over $F_{p}$ . We establish a nontrivial estimate on the incomplete character sum

\sum_{x \in \prod_{i = 1}^{n} [a_{i}, a_{i} + H]} X (\prod_{j = 1}^{n} L_{j} (x)),

provided

H > p^{\frac{1}{4} + ε}
