QUÉ SIGNIFICA EXTENSIONALITY EN INGLÉS
Extensionalidad
En lógica, extensionalidad o igualdad extensional se refiere a principios que juzgan que los objetos son iguales si tienen las mismas propiedades externas. Está en contraste con el concepto de intensionalidad, que se refiere a si las definiciones internas de los objetos son las mismas.
