Yitang Zhang Provides Major Step Toward Long-sought Proof Involving Pairs of Prime Numbers

May 20, 2013

UNH mathematician Yitang Zhang has made a major breakthrough towards solving a centuries-old problem - the twin prime conjecture. His results show that finds that there are infinitely many pairs of prime numbers that are less than 70 million units apart. Although 70 million seems like a very large number, the existence of any finite bound, no matter how large, means that that the gaps between consecutive numbers don’t keep growing forever.

The twin prime conjecture says that there is an infinite number of such twin pairs. Some attribute the conjecture to the Greek mathematician Euclid of Alexandria, which would make it one of the oldest open problems in mathematics.

Zhang's work is expected to be published in the refereed journal Annals of Mathematics later this year.
