We discuss in this paper
arithmetic properties of the function A(n) =∑pα∥nαp. Asymptotic estimates of
A(n) reveal the connection between A(n) and large prime factors of n. The
distribution modulo 2 of A(n) turns out to be an interesting study and congruences
involving A(n) are considered. Moreover the very intimate connection between A(n)
and the partition of integers into primes provides a natural motivation for its
study.
