embedding

1. The act or process by which one thing is embedded in another.

2. A map which, in any of several technical senses, represents the containment of one structure inside another.

   A continuous map which is also a homeomorphism between its domain and its image (considered with the subspace topology induced by its codomain).

3. An immersion which is also a topological embedding; equivalently, a diffeomorphism whose image is a submanifold of its codomain.

4. A ring homomorphism between fields (the name deriving from the fact that all such maps are injective).
