چکیده

Résumé. Soit H(x) = ∑ n≤x φ(n) n − 6 π2x. Motivé par une conjecture de Erdös, Lau a développé une nouvelle méthode et il a démontré que #{n ≤ T : H(n)H(n + 1) < 0} T. Nous considérons des fonctions arithmétiques f(n) = ∑ d|n bd d dont l’addition peut être exprimée comme ∑ n≤x f(n) = αx+ P (log(x)) + E(x). Ici P (x) est un polynôme, E(x) = − ∑ n≤y(x) bn n ψ ( x n ) + o(1) avec ψ(x) = x − bxc − 1/2. Nous généralisons la méthode de Lau et démontrons des résultats sur le nombre de changements de signe pour ces termes d’erreur.

Sign changes of error terms related to arithmetical functions

Let H(x) = ∑ n≤x φ(n) n − 6 π2x. Motivated by a conjecture of Erdös, Lau developed a new method and proved that #{n ≤ T : H(n)H(n + 1) < 0} T. We consider arithmetical functions f(n) = ∑ d|n bd d whose summation can be expressed as ∑ n≤x f(n) = αx+P (log(x))+E(x), where P (x) is a polynomial, E(x) = − ∑ n≤y(x) bn n ψ ( x n ) + o(1) and ψ(x) = x− bxc − 1/2. We generalize Lau’s method and prove r...

On a Relation between Sums of Arithmetical Functions and Dirichlet Series

We introduce a concept called good oscillation. A function is called good oscillation, if its m-tuple integrals are bounded by functions having mild orders. We prove that if the error terms coming from summatory functions of arithmetical functions are good oscillation, then the Dirichlet series associated with those arithmetical functions can be continued analytically over the whole plane. We a...

Asymptotic properties of functions defined on arithmetic semigroups

Asymptotic properties of certain special arithmetical functions, like the divisor function τ(n), the sum-of-divisors function σ(n) and the Euler function φ(n) can be investigated in the general setting of arithmetical semigroups. The book of J. Knopfmacher [8] contains a detailed study of such properties, including asymptotic formulae with error estimates and extremal orders of magnitude of fun...

An inequality related to $eta$-convex functions (II)

Using the notion of eta-convex functions as generalization of convex functions, we estimate the difference between the middle and right terms in Hermite-Hadamard-Fejer inequality for differentiable mappings. Also as an application we give an error estimate for midpoint formula.
