Morphisms of schemes

Closed immersion

In algebraic geometry, a closed immersion of schemes is a morphism of schemes that identifies Z as a closed subset of X such that locally, regular functions on Z can be extended to X. The latter condition can be formalized by saying that is surjective. An example is the inclusion map induced by the canonical map . (Wikipedia).
