Functor represented by a schemeIn 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 (up to natural bijections) the set of all morphisms . The scheme X is then said to represent the functor and that classify geometric objects over S given by F. The best known example is the Hilbert scheme of a scheme X (over some fixed base scheme), which, when it exists, represents a functor sending a scheme S to a flat family of closed subschemes of .
Islamic studiesIslamic studies refers to the academic study of Islam, and generally to academic multidisciplinary "studies" programs—programs similar to others that focus on the history, texts and theologies of other religious traditions, such as Eastern Christian Studies or Jewish Studies but also fields such as (environmental studies, Middle East studies, race studies, urban studies, etc.)—where scholars from diverse disciplines (history, culture, literature, art) participate and exchange ideas pertaining to the particular field of study.
