On Certain Arithmetic Functions [PDF]

open access: yes, 2000
In the recent book there appear certain arithmetic functions which are similar to the Smarandache function. In a recent paper we have considered certain generalization or duals of the Smarandache function.

A Universal Approximation Method and Optimized Hardware Architectures for Arithmetic Functions Based on Stochastic Computing

open access: yesIEEE Access, 2020
Stochastic computing (SC) has been applied on the implementations of complex arithmetic functions. Complicated polynomial-based approximations lead to large hardware complexity of previous SC circuits for arithmetic functions.

Provably Total Functions of Arithmetic with Basic Terms [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
A new characterization of provably recursive functions of first-order arithmetic is described. Its main feature is using only terms consisting of 0, the successor S and variables in the quantifier rules, namely, universal elimination and existential ...

Interactive Realizability and the elimination of Skolem functions in Peano Arithmetic [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We present a new syntactical proof that first-order Peano Arithmetic with Skolem axioms is conservative over Peano Arithmetic alone for arithmetical formulas.

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.

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).
