Olivier Ramaré

From Wikipedia, the free encyclopedia

Olivier Ramaré is a French mathematician who teaches at the Université des Sciences et Technologies de Lille.

In 1995, he proved that every even number is a sum of at most six primes. This result may be compared with Goldbach's conjecture, which states that every even number except 2 is the sum of two primes. The truth of Ramaré's result for all sufficiently large even numbers is a consequence of Vinogradov's theorem, whereas the full result follows from Goldbach's weak conjecture.
