WebSep 2, 2010 · A simplified answer is that primitive recursive functions are those which are defined in terms of other primitive recursive functions, and recursion on the structure of natural numbers. Natural numbers are conceptually like this: data Nat = Zero Succ Nat -- Succ is short for 'successor of', i.e. n+1 This means you can recurse on them like this: WebIf a = 0 then f ( x) = x is the identity function, and this is known to be primitive recursive. Indeed f ( x) = P 1 1 ( x). Now let us proceed by induction and suppose that f n ( x) = x + n is primitive recursive. By S we denote the successor function S ( k) = k + 1 which is … WebIf you know that f, π, g are primitive recursive functions prove that h defined as: h(0, y) ≃ f(y) h(x + 1, y) ≃ g(x, y, h(x, π(x, y))) is also primitive recursive function.
