Wikipedia states that homomorphisms are structure preserving maps from one algebraic structure to another.
A homeomorphism is a topology-preserving map from one topological space to another (that also admits an inverse).
However, since a topological space is a mathematical structure but not an algebraic structure, that would mean that a homeomorphism is not a homomorphism (though it is an isomorphism).
Is that true, or should I ignore wikipedia and assume that the term homomorphism can also apply to maps on non-algbraic structures?
