The atlas's own conjecture-become-theorem precedent, carried here as a theorem rather than a conjecture because it is now proved, with both ends of its 358-year history on record: Pierre de Fermat's 1637 marginal claim to a proof too large for the margin to hold, and Andrew Wiles's corrected 1995 proof, produced with Richard Taylor after a gap found in Wiles's original 1993 announcement. No trace of any proof by Fermat himself survives, and mathematicians generally believe the elementary methods available in 1637 could not have proved the general case; Sophie Germain, among others, proved significant partial results toward it in the intervening centuries. Wiles's proof works by establishing enough of a separate, deep conjecture, the modularity theorem linking elliptic curves and modular forms, to force Fermat's claim as a consequence.
Facts
StatementNo three positive integers a, b and c can satisfy the equation a to the n plus b to the n equals c to the n, for any integer value of n strictly greater than two. 1 Proof YearWiles announced a proof in June 1993; reviewers found a gap the same year, and the corrected proof, with Richard Taylor, was published in 1995.

After 358 years of effort by mathematicians, the first successful proof was released in 1994 by Andrew Wiles and formally published in 1995.

In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that there are no positive integers a, b, c, n with n > 2 such that a^n + b^n = c^n.

The proof's method of identification of a deformation ring with a Hecke algebra (now referred to as an R=T theorem) to prove modularity lifting theorems has been an influential development in algebraic number theory.
