  • The topology on the countable product of the two-point space '' D '' is induced by the metric The Cantor set may be embedded in the unit interval by the map which is a homeomorphism onto the subset of the unit interval obtained by iteratively deleting the middle third of each interval compact.

  • The Cantor set is [[homeomorphism | homeomorphic]] to a product of [[countable set | countably]] many copies of a two-point space with the [[discrete metric]].

  • While the existence of a homeomorphism between manifolds demonstrates the existence of a diffeomorphism between them if they are of dimension it is possible to construct objects which are homeomorphic and not diffeomorphic - such objects are called "exotic
