Modules des variétés abéliennes et variétés de Shimura. (French) Zbl 0538.14030

Variétés de Shimura et fonctions L, Publ. Math. Univ. Paris VII, No. 6, 21-42 (1979).
[For the entire collection see Zbl 0517.00003.]
This seminar talk claims no originality but is a clean and explicit exposition. It starts with a description of the objects studied in the seminar namely abelian varieties X provided with an action of an order of a quaternion algebra B over a totally real number field E such that \(\dim X=g=2(E:{\mathbb{Q}})\). A review of the structure and properties of End(X) is first given. Then a universal family is carefully constructed from which a coarse moduli space is derived. All of this in the complex analytic framework. In § 3, the adelic interpretation is given.
