I'm looking for an axiomatization of the natural numbers similar to ZFC or the standard axiomatization of set theory in the language of the first order predicate calculus such that the axiomatization only has one unique model of countable cardinality. I want one that excludes the nonstandard models of the natural numbers. Can anyone cite a reference?
