Complex rotation numbers

open access: yesJournal of Modern Dynamics, 2015
We investigate the notion of complex rotation number which was introduced by V.I.Arnold in 1978. Let $f: \mathbb R/\mathbb Z \to \mathbb R/\mathbb Z$ be an orientation preserving circle diffeomorphism and let $ω\in \mathbb C/\mathbb Z$ be a parameter with positive imaginary part.

Stress State of Elastic Thick-Walled Ring With Self-Balanced Pressures Distributed on Its Internal and External Borders

open access: yesVestnik Volgogradskogo Gosudarstvennogo Universiteta. Serija 1. Mathematica. Physica, 2015
For the first time with the help of the theory of analytic functions and Kolosov-Muskhelishvili formulas the problem of the two-dimensional theory of elasticity for a thickwalled ring with the uneven pressures, acting on its borders, was solved.

On Harmonic Complex Balancing Numbers

open access: yesMathematics, 2022
In the present work, we define harmonic complex balancing numbers by considering well-known balancing numbers and inspiring harmonic numbers. Mainly, we investigate some of their basic characteristic properties such as the Binet formula and Cassini ...

A Quantum-Based Similarity Method in Virtual Screening

open access: yesMolecules, 2015
One of the most widely-used techniques for ligand-based virtual screening is similarity searching. This study adopted the concepts of quantum mechanics to present as state-of-the-art similarity method of molecules inspired from quantum theory.

A Note on Generalized Hybrid Tribonacci Numbers

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we introduce the generalized hybrid Tribonacci numbers. These numbers can be considered as a generalization of the generalized complex Tribonacci, generalized hyperbolic Tribonacci and generalized dual Tribonacci numbers.

On Complex Numbers in Higher Dimensions

open access: yesAxioms, 2022
The geometric approach to generalized complex and three-dimensional hyper-complex numbers and more general algebraic structures being based upon a general vector space structure and a geometric multiplication rule which was only recently developed is ...

Complexity of natural numbers

open access: yes, 2021
This is the English version of the paper: "Complejidad de los n meros naturales", Gaceta de la Real Sociedad Matem tica Espa ola 3 (2000) 230--250. In this paper, several conjectures about the complexity of natural numbers are proposed. In a recent joint paper with H.

p-adic numbers encode complex networks

open access: yesScientific Reports, 2021
The Erdős-Rényi (ER) random graph G(n, p) analytically characterizes the behaviors in complex networks. However, attempts to fit real-world observations need more sophisticated structures (e.g., multilayer networks), rules (e.g., Achlioptas processes ...

The Complexity of Number Theory

open access: yes, 2020
The Goldbach's conjecture has been described as the most difficult problem in the history of Mathematics. This conjecture states that every even integer greater than 2 can be written as the sum of two primes. This is known as the strong Goldbach's conjecture.
