Olivier Ramaré is a French mathematician who teaches at the Université des Sciences et Technologies de Lille. This article is about the country For a topic outline on this subject see List of basic France topics. A mathematician is a person whose primary area of study and research is the field of Mathematics. The Université des Sciences et Technologies de Lille (USTL or Université de Lille I is a French University established in 1854 in Lille with
In 1995, he proved that every even number is a sum of at most six primes. In Mathematics, a proof is a convincing demonstration (within the accepted standards of the field that some Mathematical statement is necessarily true In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1 This result may be compared with Goldbach's conjecture, which states that every even number except 2 is the sum of two primes. Goldbach's conjecture is one of the oldest unsolved problems in Number theory and in all of Mathematics. 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. In Mathematics, in the field of Number theory, Vinogradov's theorem states that any Sufficiently large odd Integer can be written as a sum of In Number theory, Goldbach's weak conjecture, also known as the odd Goldbach conjecture, the ternary Goldbach problem, or the 3-primes problem
