Primitive recursive arithmetic
WebPrimitive recursive arithmetic, or PRA, is a quantifier-free formalization of the natural numbers. It was first proposed by Skolem as a formalization of his finitist conception of the foundations of arithmetic, and it is widely agreed that all reasoning of PRA is finitist. WebFeb 8, 2024 · Recall that a subset S ⊆ ℕ n is called primitive recursive if its characteristic function φ S is primitive recursive. If we take S = {m}, then φ S = d m. Furthermore, a predicate Φ (𝒙) over ℕ k is primitive recursive if the corresponding set S (Φ):= {𝒙 ∈ ℕ k ∣ Φ (𝒙)} is primitive recursive. •
