The Distribution of Prime Numbers

open access: yes, 2022
In this paper, we discovered a new sequence of all prime numbers which end with a 1 or 9, the sequence defined by 𝑎(𝑛) = (𝑛^2 − 𝑛 − 1)/gcd (𝑏(𝑛), 𝑛^2 − 𝑛 − 1), with 𝑏(𝑛) satisfying the recurcive formula 𝑏(𝑛)=(𝑛 − 1). 𝑏(𝑛 − 1) − 𝑛. 𝑏(𝑛 − 2) and 𝑏(1) = 𝑏(2) = −1, the sequence 𝑎(𝑛) takes only 1’s and primes.

A conceptual proposal on the undecidability of the distribution law of prime numbers and theoretical consequences

open access: yesRatio Mathematica, 2019
Within the conceptual framework of number theory, we consider prime numbers and the classic still unsolved problem to find a complete law of their distribution.

On mixed joint discrete universality for a class of zeta-functions: a further generalization

open access: yesMathematical Modelling and Analysis, 2020
We present the most general at this moment results on the discrete mixed joint value-distribution (Theorems 5 and 6) and the universality property (Theorems 3 and 4) for the class of Matsumoto zeta-functions and periodic Hurwitz zeta-functions under ...

On the numbers that determine the distribution of twin primes [PDF]

open access: yesSurveys in Mathematics and its Applications, 2018
This paper is about a class of numbers indirectly connected to the twin primes, which have not been investigated so far. With the help of these numbers, we look at the set of twin primes from a different perspective and bring the reader's attention to ...

Investigating Schema-Free Encoding of Categorical Data Using Prime Numbers in a Geospatial Context

open access: yesISPRS International Journal of Geo-Information, 2019
Prime numbers are routinely used in a variety of applications, e.g., cryptography and hashing. A prime number can only be divided by one and the number itself.

A Numerical Study on the Regularity of d-Primes via Informational Entropy and Visibility Algorithms

open access: yesComplexity, 2020
Let a d-prime be a positive integer number with d divisors. From this definition, the usual prime numbers correspond to the particular case d=2. Here, the seemingly random sequence of gaps between consecutive d-primes is numerically investigated.

On positive sequences of reals whose block sequence has an asymptotic distribution function [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this paper we study the properties of the unbounded sequence 0≤y₁≤y₂≤y₃≤... of positive reals having asymptotic distribution function of the form x^λ.

On Joint Universality in the Selberg–Steuding Class

open access: yesMathematics, 2023
The famous Selberg class is defined axiomatically and consists of Dirichlet series satisfying four axioms (Ramanujan hypothesis, analytic continuation, functional equation, multiplicativity).
