What nationality was the mathematician who proposed the Legendre's conjecture?
Legendre's conjecture Legendre's conjecture, proposed by Adrien-Marie Legendre, states that there is a prime number between "n" and ("n" + 1) for every positive integer "n". The conjecture is one of Landau's problems (1912) on prime numbers; as of 2017 , the conjecture has neither been proved nor disproved.
