Abstract: Proofs in an arithmetic system are ranked according to a ramification hierarchy based on
occurrences of induction. It is shown that this ranking of proofs corresponds exactly to a
natural ranking of the primitive recursive functions based on occurrences of recursion. A
function is provably convergent using a rank r proof, if and only if it is a rank r function.
The result is of interest to complexity theorists, since rank one corresponds to polynomial
time. Remarkably, this characterization of... (Update)
