Abstract

A result of Ehrenfeucht implies that the smelliest class of number- theoretic functions(formula presented) containing the constants 0, 1, 2, the identity function X, and closed under addition, multiplication and(formula presented) c is well- ordered by the relation of eventual dominance. We show that its order type is (formula presented) c, and that for any two nonzero functions /, g in the class the quotient (formula presented) tends to a limit in E+ U{0, oo) as n(formula presented) c where E+ is the smallest set of positive real numbers containing 1 and closed under addition, multiplication and under the operations(formula presented).
