Abstract. Based on the characterization of the set of natural numbers by the recursion property, developed in [2], we prove in a general setting that the properties of recursion, induction and well-foundedness are equivalent for a given set. This result is extended to classes and is used to give another proof of the characterization of the set of natural numbers by recursion.

Palabras clave : recursion; induction; well-founded order.
