homomorphism <mathematics>

relationship between two domains such that there is a structure-preserving function from one to the other

Note to entry: A homomorphism is distinct from a isomorphism in that no inverse function is required. In an isomorphism, there are two homomorphisms that are functional inverses of one another. Continuous functions are topological homomorphisms because they preserve "topological characteristics". The mapping of topological complexes to their geometric realizations preserves the concept of boundary and is therefore a homomorphism.

homomorfismo <matematicas>

relación entre dos dominios de tal manera que hay una función de preservación de la estructura de uno a otro

Nota: Un homomorfismo se distingue de un isomorfismo en que no se requiere una función inversa. En un isomorfismo, hay dos homomorfismos que son funcionales inversos el uno del otro. Las funciones continuas son homomorfismos topológicos porque conservan "características topológicas". La asignación de los complejos topológicos a sus realizaciones geométricas preserva el concepto de frontera y es, por lo tanto, un homomorfismo.
