Arthur Parameters and Fourier coefficients for Automorphic Forms on Symplectic Groups
[Paramètres d’Arthur et coefficients de Fourier des formes automorphes sur des groupes symplectiques]
Annales de l'Institut Fourier, Tome 66 (2016) no. 2, pp. 477-519.

Nous étudions la structures des coefficients de Fourier des formes automorphes sur des groupes symplectiques à partir de leurs structures locale et globale liée aux paramètres d’Arthur. Ceci est la première étape pour prouver une conjecture du premier auteur concernant le lien entre la structure des coefficients de Fourier et les paramètres d’Arthur pour les formes automorphes dans le spectre discret.

We study the structures of Fourier coefficients of automorphic forms on symplectic groups based on their local and global structures related to Arthur parameters. This is a first step towards the general conjecture on the relation between the structure of Fourier coefficients and Arthur parameters for automorphic forms occurring in the discrete spectrum, given by the first named author.
