Variants on Andrica’s Conjecture with and without the Riemann Hypothesis

open access: yesMathematics, 2018
The gap between what we can explicitly prove regarding the distribution of primes and what we suspect regarding the distribution of primes is enormous. It is (reasonably) well-known that the Riemann hypothesis is not sufficient to prove Andrica’s ...

Two prime or not two prime

open access: yesNature Catalysis, 2018
The carboxylation of aromatic compounds with CO2 is an attractive reaction, albeit limited in scope. Now, bulky ligands in a Rh(II) catalysed C–H carboxylation of 2-arylphenols are shown to override the standard ortho/para Kolbe-Schmitt-type regioselectivity allowing instead carboxylation at 2’

The integral part of a nonlinear form with a square, a cube and a biquadrate

open access: yesOpen Mathematics, 2020
In this paper, we show that if λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} are non-zero real numbers, and at least one of the numbers λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} is irrational, then the integer parts of λ1n12+λ2n23+λ3n34{

Create your own stimulus: Manipulating movements according to social categories. [PDF]

open access: yesPLoS ONE, 2017
People ascribe purposeful behaviour to the movements of artificial objects and social qualities to human body motion. We investigated how people associate simple motion cues with social categories.

A Note on Short Intervals Containing Primes [PDF]

open access: yes, 2004
In 1999, P. Dusart showed that for x ≥ 3275, there exists at least a prime number in the interval (x, x(1 + 1/(2ln²x))] and in 2003, O. Ramaré and Y. Saouter showed that for x ≥ 10726905041 there exists at least a prime number in the interval (x(1 −

ON SHIFTED PRIMES AND BALANCED PRIMES [PDF]

open access: yesInternational Journal of Number Theory, 2012
The asymptotic order of the number of primes, which are such that the shift by a fixed integer is a number supported by a given set of primes times a coprime squarefree number, is determined. The order is also determined when the shift and its negative have this same shape.

Prime numbers in logarithmic intervals [PDF]

open access: yes, 2010
Let $X$ be a large parameter. We will first give a new estimate for the integral moments of primes in short intervals of the type $(p,p+h]$, where $p\leq X$ is a prime number and $h=\odi{X}$.

About twin primes and distribution of primes [PDF]

open access: yes, 2010
This paper give us a demonstration of twin primes conjecture using approximation of function (iupsilon) that we introduce in section 6. Section 1-5 give us introduction to terminology and a clarification on (iupsilon) terms.
