 In mathematics, an embedding (or imbedding) is one instance of some mathematical structure contained within another instance, such as a group that is a subgroup. When some object X is said to be embedded in another object Y, the embedding is given by some injective and structurepreserving map f : X → Y. The precise meaning of "structurepreserving" depends on the kind of mathematical structure of which X and Y are instances. In the terminology of category theory, a structurepreserving map is called a morphism. The fact that a map f : X → Y is an embedding is often indicated by the use of a "hooked arrow", thus: On the other hand, this notation is sometimes reserved for inclusion maps. Given X and Y, sev brother ink cartridgesintercom
