Sums of distinct divisors and sums of distinct units
where the d are distinct positive divisors of M. Clearly a (M1) ?< o(M). In a recent paper [1], B. M. Stewart presented a structure theorem for the set S of integers M, for which ac(M) =oa(M). In this paper we will drop the restriction that the divisors need be …
