Asymptotic formulas for generalized gcd-sum and lcm-sum functions over r-regular integers (mod n<sup>r</sup>)

In this paper we perform a further investigation for r-gcd-sum function over r-regular integers (mod n<sup>r</sup>), and we derive two kinds of asymptotic formulas by making use of Dirichlet product, Euler product and some techniques. Moreover, we also establish estimates for the general...

Description
Summary:In this paper we perform a further investigation for r-gcd-sum function over r-regular integers (mod n<sup>r</sup>), and we derive two kinds of asymptotic formulas by making use of Dirichlet product, Euler product and some techniques. Moreover, we also establish estimates for the generalized r-lcm-sum function over r-regular integers (mod n).
