topological embedding


Let X, Y be topological spacesMathworldPlanetmath. A map f:XY is said to be an embeddingMathworldPlanetmathPlanetmath (or imbedding) if the restrictionPlanetmathPlanetmathPlanetmath f:Xf[X] is homeomorphismPlanetmathPlanetmath.

The notation f:XY is often used for embeddings.

The embeddings correspond to the subspacesMathworldPlanetmath. Observe that f and the inclusion mapMathworldPlanetmath of the subspace f[X] into X differ only up to a homeomorphism.
