Fermat's last theorem

Fermat's last theorem
/fer mahz"/, Math.
the unproved theorem that the equation xn + yn = zn has no solution for x, y, z nonzero integers when n is greater than 2.
[1860-65; named after P. de FERMAT]

Statement that there are no natural numbers x, y, and z such that xn + yn = zn, in which n is a natural number greater than 2.

About this, Pierre de Fermat wrote in 1637 in his copy of Diophantus's Arithmetica, "I have discovered a truly remarkable proof but this margin is too small to contain it." Although the theorem was subsequently shown to be true for many specific values of n, leading to important mathematical advances in the process, the difficulty of the problem soon convinced mathematicians that Fermat never had a valid proof. In 1995 the British mathematician Andrew Wiles (b. 1953) and his former student Richard Taylor (b. 1962) published a complete proof, finally solving one of the most famous of all mathematical problems.

also called  Fermat's great theorem 

      the statement that there are no natural numbers (1, 2, 3, …) x, y, and z such that xn + yn = zn, in which n is a natural number greater than 2. For example, if n = 3, Fermat's theorem states that no natural numbers x, y, and z exist such that x3 + y 3 = z3 (i.e., the sum of two cubes is not a cube). In 1637 the French mathematician Pierre de Fermat (Fermat, Pierre de) wrote in his copy of the Arithmetica by Diophantus of Alexandria (c. AD 250), “I have discovered a truly remarkable proof [of this theorem] but this margin is too small to contain it.” For centuries mathematicians were baffled by this statement, for no one could prove or disprove Fermat's theorem. Proofs for many specific values of n were devised, however, and by 1993, with the help of computers, it was confirmed for all n < 4,000,000. Using sophisticated tools from algebraic geometry, the English mathematician Andrew Wiles (Wiles, Andrew John), with help from his former student Richard Taylor, devised a proof of Fermat's last theorem that was published in 1995 in the journal Annals of Mathematics.
