Soit K un corps quadratique imaginaire. Soit Π (resp. Π) une représentation cuspidale régulière algébrique de GLn(AK) (resp. GLn1(AK)), qui est, de plus, cohomologique et auto-duale. Si Π est une induction automorphe cyclique d'un caractère de Hecke χ sur un corps CM, on montre les relations entre les périodes automorphes de Π définies par Harris et celles de χ. Par conséquent, on affine une formule de Grobner et Harris pour les valeurs critiques de L(s,Π×Π), L étant la fonction de Rankin–Selberg. Cela complète la démonstration d'une version automorphe de la conjecture de Deligne dans certains cas.

Let K be a quadratic imaginary field. Let Π (resp. Π) be a regular algebraic cuspidal representation of GLn(AK) (resp. GLn1(AK)), which is moreover cohomological and conjugate self-dual. When Π is a cyclic automorphic induction of a Hecke character χ over a CM field, we show relations between automorphic periods of Π defined by Harris and those of χ. Consequently, we refine a formula given by Grobner and Harris for critical values of the Rankin–Selberg L-function L(s,Π×Π). This completes the proof of an automorphic version of Deligne's conjecture in certain cases.
