topological embedding
Let , be topological spaces. A map is said to be an embedding
(or imbedding) if the restriction
is homeomorphism
.
The notation is often used for embeddings.
The embeddings correspond to the subspaces. Observe that and the inclusion map
of the subspace into differ only up to a homeomorphism.
