Functor represented by a scheme
text:
In algebraic geometry, a functor represented by a scheme X is a set-valued contravariant functor on the category of schemes such that the value of the functor at each scheme S is the set of all morphisms S → X. The functor F is then said to be naturally equivalent to the functor of points of X; and the scheme X is said to represent the functor F, and to classify geometric objects over S given by F. A functor producing certain geometric objects over S might be represented by a scheme X. For examp
