homeomorphism


A homeomorphism f of topological spacesMathworldPlanetmath is a continuousMathworldPlanetmathPlanetmath, bijectiveMathworldPlanetmathPlanetmath map such that f-1 is also continuous. We also say that two spaces are homeomorphic if such a map exists.

If two topological spaces are homeomorphic, they are topologically equivalent — using the techniques of topology, there is no way of distinguishing one space from the other.

An autohomeomorphism (also known as a self-homeomorphism) is ahomeomorphism from a topological space to itself.
