Arithmetical properties of generalized Ramanujan sums

Tom M. (Mike) Apostol

Vol. 41 (1972), No. 2, 281–293
Abstract

The sums studied in this paper are defined as follows. For any two arithmetical functions f and g, let

            ∑
Sf,g(m,k) =      f(d)g(k∕d),
d|(m.k)
(1)

where the sum extends over the divisors of the greatest common divisor (m,k) of the positive integers m and k. It should be noted that m and k do not enter symmetrically in (1) unless g is constant.
