A note in the margin

"x² + y² = z² has infinitely many integer solutions, but for n ≥ 3 there are none." Fermat's marginal note became public in a posthumous 1670 edition. Wiles worked privately from 1986, announced a result in 1993, and repaired a gap with Richard Taylor in 1994. The two papers appeared in the 1995 Annals of Mathematics.
Year | Person | Advance |
|---|---|---|
1637 | Fermat | Conjectured in a book margin (a copy of Diophantus) |
1770 | Euler | Proof for n = 3 (though a gap was later found) |
1825 | Dirichlet and Legendre | n = 5 |
1839 | Lamé | n = 7 (using Germain’s theorem) |
1908 | Wolfskehl Prize | 100,000-mark prize — inspired countless false proofs |
1955 | Taniyama–Shimura conjecture | Conjectured that every elliptic curve is modular |
1982 | Frey | Proposed that an FLT counterexample ⇒ a non-modular elliptic curve |
1986 | Ribet | Proved the epsilon conjecture → completed the bridge between FLT and Taniyama–Shimura |
1993 announcement / 1994 repair / 1995 publication | Andrew Wiles (+ Richard Taylor) | Two papers completed the argument after years of concentrated private work |
The simplest-looking statement took 358 years to solve — and the solution came from entirely different fields: elliptic curves and modular forms.
No integer solutions for x^n + y^n = z^n when n>2 — Fermat's 1637 margin note, finally proved by Wiles in 1994.
Q.n=2: 3² + 4² = ?
Q.n=3: are there positive integer solutions to x³ + y³ = z³?
