On Sums of Sums Involving the Von Mangoldt Function

Abstract

Let \(\Lambda \) denote the von Mangoldt function, and (n, q) be the greatest common divisor of positive integers n and q. For any positive real numbers x and y, we shall consider several asymptotic formulas for sums of sums involving the von Mangoldt function; \( S_{k}(x,y):=\sum _{n\le y}\left( \sum _{q\le x}\right. \left. \sum _{d|(n,q)}d\Lambda \left( \frac{q}{d}\right) \right) ^{k} \) for \(k=1,2\).
