Twin prime. A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (17, 19) or (41, 43). In other words, a twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime ...
Dr. Sacks meets twin brothers who can neither read nor perform multiplication, yet are playing a "game" of finding very large prime numbers. While the twins were able to spontaneously generate these numbers, from six to twenty digits, Sacks had to resort to a book of prime numbers to join in with them.
A prime gap is the difference between two successive prime numbers. The n -th prime gap, denoted gn or g ( pn) is the difference between the ( n + 1)-st and the n -th prime numbers, i.e. We have g1 = 1, g2 = g3 = 2, and g4 = 4. The sequence ( gn) of prime gaps has been extensively studied; however, many questions and conjectures remain ...
9780198788287. Closing the Gap: The Quest to Understand Prime Numbers is a book on prime numbers and prime gaps by Vicky Neale, published in 2017 by the Oxford University Press ( ISBN 9780198788287 ). The Basic Library List Committee of the Mathematical Association of America has suggested that it be included in undergraduate mathematics libraries.
Conjecture. The real part (red) and imaginary part (blue) of the Riemann zeta function along the critical line Re ( s) = 1/2. The first non-trivial zeros can be seen at Im ( s) = ±14.135, ±21.022 and ±25.011. The Riemann hypothesis, a famous conjecture, says that all non-trivial zeros of the zeta function lie along the critical line.
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a ...
The first Hardy–Littlewood conjecture predicts there are infinitely many of these. In number theory, the first Hardy–Littlewood conjecture [1] states the asymptotic formula for the number of prime k-tuples less than a given magnitude by generalizing the prime number theorem. It was first proposed by G. H. Hardy and John Edensor Littlewood ...
prime number 1. A prime number is a positive integer with no divisors other than itself and 1. 2. The prime number theorem describes the asymptotic distribution of prime numbers. profinite A profinite integer is an element in the profinite completion ^ of along all integers.
