Title: Shimura Varieties of PEL type and of Abelian type

Abstract: We will continue to talk about Shimura datum of PEL type. Then we will talk about SVs of Abelian type.

Title: Shimura Variety of Hodge Type

Abstract: We will recall Siegel Modular Variety we learned last time. Then we will try to explain the relation between this variety and the moduli of principally polarized abelian variety with a level structure. Finally we will give the explain the general definition of Shimura Variety of Hodge Type.

Title: The Siegel modular variety

Abstract: We will study the basic example of Shimura varieties, the Siegel modular variety. If time permits, I will study the Shimura varieties of Hodge type.

Title: To general Shimura varieties

Abstract: We explain how to pass from the notion of connected Shimura varieties to general ones. This part also covers in a second time, the structure of a Shimura varieties and zero dimensional ones Of a Shimura Variety.

Title: Connected Shimura varieties
Abstract: I will try to explain what a connected Shimura variety is, from two point of views: defined by congruence conditions as well as an ad\`elic description for it.

Title: Motivating  the notion of a Shimura variety
Abstract: A Shimura  variety is in first approximation  the quotient of a certain type of homogeneous space by an arithmetic group and  which is defined over a specific number field. It is a natural generalization of the  classical example of the upper half plane divided out by the integral modular group (that yields the j-line).
We shall give some examples to illustrate this notion.
