Twin prime - Wikipedia
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 twin or ...
2.7: Theorems and Conjectures involving prime numbers
The \(n^2+1\) Conjecture. There are infinitely many primes of the form \(n^2+1\), where \(n\) is a positive integer.
Theorems and Conjecture related to Prime Numbers
2024年10月25日 · Prime numbers are unique integers greater than 1 that can only be divided by 1 and themselves, with various theorems revealing their infinite nature and distribution patterns.
2006年12月12日 · Twin primes are primes of the form (p, p + 2). There are many proofs for the infinitude of prime numbers, but it is very difficult to prove whether there are an infinite number of pairs of twin primes.
Prime Conjectures and Open Questions - PrimePages
Below are just a few of the many conjectures concerning primes. Goldbach's Conjecture: Every even n > 2 is the sum of two primes. Goldbach wrote a letter to Euler in 1742 suggesting that every integer n > 5 is the sum of three primes.

Twin prime conjecture | Progress & Definition | Britannica
twin prime conjecture, in number theory, assertion that there are infinitely many twin primes, or pairs of primes that differ by 2. For example, 3 and 5, 5 and 7, 11 and 13, and 17 and 19 are twin primes. As numbers get larger, primes become less frequent and twin primes rarer still.

2024年6月7日 · Danish author Jan Egesborg has endeavored to introduce children to one of the most stubborn open problems in number theory, which even the brightest minds have repeatedly failed to solve over the...
Twin Prime Conjecture -- from Wolfram MathWorld
There are two related conjectures, each called the twin prime conjecture. The first version states that there are an infinite number of pairs of twin primes (Guy 1994, p. 19). It is not known if there are an infinite number of such primes (Wells 1986, p. 41; Shanks 1993, p. 30), but it seems almost certain to be true.
The Twin Prime Conjecture - UNC Greensboro
Twin Prime Conjecture. There are infinitely many primes \(p\) such that \(p + 2\) is also prime. This is the first (and only) conjecture that you will encounter in this course.
