Definition

Two topological spaces, [ilmath](X,\mathcal{ J })[/ilmath] and [ilmath](Y,\mathcal{ K })[/ilmath], are said to be homeomorphic if there exists a homeomorphism between them. Recall a homeomorphism a continuous bijection with a continuous inverse.

A homeomorphism is an isomorphism in the TOP category, as such it is an equivalence relation on the morphisms (which are continuous maps) between [ilmath](X,\mathcal{ J })[/ilmath] and [ilmath](Y,\mathcal{ K })[/ilmath].

More information may be found on the homeomorphism page
