WebMay 5, 2015 · The theorem says that if F steps to F' in several steps, for all A, ap F A steps to ap F' A in many steps. The actual proof is quite boring, we just recurse and apply step/ap1 until everything type checks. Note that the world specification for step*/left is a little strange.

Sets A function, f, is said to be partial recursive if there is a ’-program for it. Theorem 1 There is a total function that is not recursive. Proof: Deﬁne f as follows: for every x 2 N, f(x) = ’x(x)+1 if ’x(x) #; 0 if ’x(x)" : It is clear that f is total.
