If is injective, then is said to be an immersion at x. If is an immersion at every point, it is called an immersion.
If the image of is also closed, then is called a closed immersion.
The notion of closed immersion (http://planetmath.org/ClosedImmersion) for schemes is the analog of this notion in algebraic geometry.
