New Proof That the Sum of the Reciprocals of Primes Diverges

open access: yesMathematics, 2020
In this paper, we give a new proof of the divergence of the sum of the reciprocals of primes using the number of distinct prime divisors of positive integer n, and the placement of lattice points on a hyperbola given by n=pr with prime number p.

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.

Semantic priming, prime reportability, and retroactive priming are interdependent [PDF]

open access: yesMemory & Cognition, 1988
In two experiments, semantic analysis of prime words was measured in terms of facilitation in naming a semantically related target word. Targets were degraded but gradually clarified until the subject named them. Subjects reported the prime after naming the target. Experiment 1 used semantic associates as primes at a 50-msec prime-target stimulus onset

On a density problem of Erdös

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
For a positive integer n, let P(n) denotes the largest prime divisor of n and define the set: 𝒮(x)=𝒮={n≤x:n   does not divide   P(n)!}. Paul Erdös has proposed that |S|=o(x) as x→∞, where |S| is the number of n∈S. This was proved by Ilias Kastanas.

Restriction theory of the Selberg sieve, with applications [PDF]

open access: yes, 2004
The Selberg sieve provides majorants for certain arithmetic sequences, such as the primes and the twin primes. We prove an L^2-L^p restriction theorem for majorants of this type.

Centered Polygonal Lacunary Graphs: A Graph Theoretic Approach to p-Sequences of Centered Polygonal Lacunary Functions

open access: yesMathematics, 2019
This work is on the nature and properties of graphs which arise in the study of centered polygonal lacunary functions. Such graphs carry both graph-theoretic properties and properties related to the so-called p-sequences found in the study of centered ...

Shifting evaluation windows: predictable forward primes with long SOAs eliminate the impact of backward primes. [PDF]

open access: yesPLoS ONE, 2013
Recent work suggests that people evaluate target stimuli within short and flexible time periods called evaluation windows. Stimuli that briefly precede a target (forward primes) or briefly succeed a target (backward primes) are often included in the ...

The primes contain arbitrarily long arithmetic progressions [PDF]

open access: yes, 2004
We prove that there are arbitrarily long arithmetic progressions of primes. There are three major ingredients. The first is Szemeredi s theorem, which asserts that any subset of the integers of positive density contains progressions of arbitrary length ...

Primes in Intervals and Semicircular Elements Induced by p-Adic Number Fields Q p over Primes p

open access: yesMathematics, 2019
In this paper, we study free probability on (weighted-)semicircular elements in a certain Banach *-probability space ( LS , τ 0 ) induced by measurable functions on p-adic number fields Q p over primes p .
