Sums of averages of gcd-sum functions II

Lisa Kaltenböck, Isao Kiuchi, Sumaia Saad Eddin +1

Let $g cd (k, j)$ denote the greatest common divisor of the integers $k$ and $j$ , and let $r$ be any fixed positive integer. Define $$ M_r(x; f) := \sum_{k\leq x}\frac{1}{k^{r+1}}\su…

On the distribution of products of two primes

Sumaia Saad Eddin, Yuta Suzuki

For a real parameter $r$ , the RSA integers are integers which can be written as the product of two primes $pq$ with $p < q \leq r p$ , which are named after the importance of products o…

On sums of logarithmic averages of gcd-sum functions

Isao Kiuchi, Sumaia Saad Eddin

Let $g cd (k, j)$ be the greatest common divisor of the integers $k$ and $j$ . For any arithmetical function $f$ , we establish several asymptotic formulas for weighted averages of gcd…
