On certain equations and inequalities involving the arithmetical functions φ(n) and d(n) – II [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In papers [3] and [5] we have studied certain equations and inequalities involving the arithmetical functions φ(n) and d(n). In this paper we will consider some other equations. Some open problems will be stated, too.

Some Properties of Euler’s Function and of the Function τ and Their Generalizations in Algebraic Number Fields

open access: yesMathematics, 2021
In this paper, we find some inequalities which involve Euler’s function, extended Euler’s function, the function τ, and the generalized function τ in algebraic number fields.

On an additive arithmetic function [PDF]

open access: yesPacific Journal of Mathematics, 1977
Let \(n\) be a positive integer, \(n=\prod\limits_{i=1}^rp_i^{\alpha_i}\) in canonical form, and let \(A(n)=\sum\limits_{i=1}^r\alpha_ip_i\). Clearly \(A\) is an additive arithmetic function.

Objects generated by an arbitrary natural number. Part 4: New aspects [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
The set Set(n), generated by an arbitrary natural number n, was defined in [3]. There, and in [5, 6], some arithmetic functions and arithmetic operators of a modal and topological types are defined over the elements of Set(n).

Some new arithmetic functions [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We introduce and study some new arithmetic functions, connected with the classical functions φ (Euler's totient), ψ (Dedekind's function) and σ (sum of divisors function).

On certain arithmetical products involving the divisors of an integer [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We study the arithmetical products Π d^d, Πd^{1/d} and Πd^{log d}, where d runs through the divisors of an integer n>1.
