Abstract
A real-valued arithmetic function f is said to cluster around a pointr if the upper density of inputs n for which f(n) is within \(\delta \) of r does not tend to zero as \(\delta \) goes to zero. If f does not cluster around any real number, then we say that f is nonclustering. We show that the product of nonclustering additive functions is nonclustering and provide a generalization for polynomials of nonclustering additive functions. We then use these results to prove that products of additive functions possessing continuous distribution functions also possess continuous distribution functions.
