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 ...

On the twin-prime problem, II [PDF]

open access: yesActa Arithmetica, 1967
The twin-prime problem, which was stated by LANDAU in his Cambridge-Congress lecture in 1912 as the second main problem of the analytical number theory asks whether or not there exists an infinity of prime-pairs (p, q) with p - q = 2 or more generally with p - q = 2l (l fixed integer).

Conjecture of twin primes (Still unsolved problem in Number Theory). An expository essay [PDF]

open access: yesSurveys in Mathematics and its Applications, 2017
The purpose of this paper is to gather as much results of advances, recent and previous works as possible concerning the oldest outstanding still unsolved problem in Number Theory (and the most elusive open problem in prime numbers) called "Twin primes ...

On the sum of partition norms and its connection to norms of partitions with parts greater than one [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We study the —the product of the parts of a partition—with emphasis on partitions whose parts all exceed 1. We obtain two bivariate recurrences for the sum of norms over partitions into distinct parts, including a refinement that separates the ...

Endodontic and dental practice during COVID-19 pandemic: Position statement from the Indian Endodontic Society, Indian Dental Association, and International Federation of Endodontic Associations

open access: yesEndodontology, 2020
The emergence of COVID-19 pandemic poses an immense global health challenge. As dental care providers, we are faced with significant responsibilities both to the dental team and our patients to limit exposure to the virus.

Positive geometry, local triangulations, and the dual of the Amplituhedron

open access: yesJournal of High Energy Physics, 2021
We initiate the systematic study of local positive spaces which arise in the context of the Amplituhedron construction for scattering amplitudes in planar maximally supersymmetric Yang-Mills theory. We show that all local positive spaces relevant for one-

Splitting Cubic Circle Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
We show that every 3-regular circle graph has at least two pairs of twin vertices; consequently no such graph is prime with respect to the split decomposition.

Catalan numbers, primes, and twin primes

open access: yesElemente der Mathematik, 2008
Dieser Artikel beabsichtigt, einige Beziehungen zwischen Catalan-Zahlen, Primzahlen und Primzahlzwillingen darzustellen, indem nur elementare arithmetische Begriffe angewendet, gleichzeitig aber auch viele (historische) Bezuge fur den an einer weiteren Ausfuhrung interessierten Leser angeboten werden.
