On the asymptotic behavior of the integral T(x)

Mihoub Bouderbala, Meselem Karras

In this paper, we estimate the integral T(x) mentioned in the title, where {t} denotes the fractional part of the real number t, and x is any positive real number.

Note on Fractional Sums with Fixed GCD

Meselem Karras

We investigate fractional sums of arithmetic functions over products of two or three integers, with emphasis on fixed greatest common divisors and multiplicative weights. Let $f$ b…

On the Mean Value of $D_{k} (n)$ in Arithmetic Progressions

Meselem Karras

Let $k \geq 2$ be a fixed integer. We define the multiplicative function $D_{k} (n) = d_{k} (n) / d_{k}^{*} (n)$ , such that $d_{k} (n)$ is the Piltz divisor function and $d_{k}^{*} (n) = k^{I ¨ (n)}$ is i…

Hyperbolic summation involving certain arithmetic functions and the integer part function

Meselem Karras

Let f be an arithmetic function satisfying certain conditions. In this paper, we give an asymptotic formula for the sum \[\sum_{n_1 n_2 \cdots n_r \leq x} f\left(\left\lfloor \frac…

Hyperbolic summation involving the function $I^c ◯ (n)$ and lcm

Meselem Karras

We study the sum $\sum_{ab c \leq x} I^c ◯ ([a, b, c])$ , where $I^c ◯ (n)$ denotes the number of distinct prime divisors of $n \in Z_{\geq 1}$ , counted with multiplicity, and where $…
