This article is an introduction to the theory of Shimura varieties or,
in other words, the arithmetic theory of automorphic functions and
holomorphic automorphic forms.
Hermitian symmetric domains; Hodge structures and their classifying
spaces; locally symmetric varieties; connected Shimura varieties;
Shimura varieties; the Siegel modular variety; Shimura varieties of
Hodge type; PEL Shimura varieties; general Shimura varieties; complex
multiplication (the Shimura-Taniyama formula and the main theorem);
definition of canonical models; uniqueness of canonical models;
existence of canonical models; abelian varieties over finite fields;
the good reduction of Shimura varieties; a formula for the number of
