 working in analytic number theory
Analytic number theory
In mathematics, analytic number theory is a branch of number theory that uses methods from mathematical analysis to solve problems about the integers. It is often said to have begun with Dirichlet's introduction of Dirichlet L-functions to give the first proof of Dirichlet's theorem on arithmetic...

where denotes the nth prime number
Prime number
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example 5 is prime, as only 1 and 5 divide it, whereas 6 is composite, since it has the divisors 2...

. In other words, for every c > 0, there exist infinitely many pairs of consecutive primes pn and pn+1 that are closer to each other than the average distance between consecutive primes by a factor of c, i.e., pn+1 − pn < c log pn.

This result was originally reported in 2003 by Dan Goldston and Cem Yıldırım but was later retracted. Then Janos Pintz joined the team and completed the proof in 2005. Later they improved this to showing that pn+1-pn<clog n(log log n)2 occurs infinitely often.

Further, if one assumes the Elliott-Halberstam conjecture
Elliott-Halberstam conjecture
In number theory, the Elliott–Halberstam conjecture is a conjecture about the distribution of prime numbers in arithmetic progressions. It has many applications in sieve theory. It is named for Peter D. T. A. Elliott and Heini Halberstam....

, then one can also show that primes within 16 of each other occur infinitely often, which is nearly the twin prime conjecture
