- Andrew Wiles, a researcher at Princeton, claims to have found a proof.
- The proof was presented in Cambridge, UK during a three day seminar to
- an audience which included some of the leading experts in the field.
- The proof was found to be wanting. In summer 1994, Prof. Wiles
- acknowledged that a gap existed. On October 25th, 1994, Prof. Andrew
- Wiles released two preprints, Modular elliptic curves and Fermat's
- Last Theorem, by Andrew Wiles, and Ring theoretic properties of
- certain Hecke algebras, by Richard Taylor and Andrew Wiles.
-
- The first one (long) announces a proof of, among other things,
- Fermat's Last Theorem, relying on the second one (short) for one
- crucial step.
-
- The argument described by Wiles in his Cambridge lectures had a
- serious gap, namely the construction of an Euler system. After trying
- unsuccessfully to repair that construction, Wiles went back to a
- different approach he had tried earlier but abandoned in favor of the
- Euler system idea. He was able to complete his proof, under the
- hypothesis that certain Hecke algebras are local complete
- intersections. This and the rest of the ideas described in Wiles'
- Cambridge lectures are written up in the first manuscript. Jointly,
- Taylor and Wiles establish the necessary property of the Hecke
- algebras in the second paper.
-
- The new approach turns out to be significantly simpler and shorter
- than the original one, because of the removal of the Euler system. (In
- fact, after seeing these manuscripts Faltings has apparently come up
- with a further significant simplification of that part of the
- argument.)
-
- The preprints were submitted to The Annals of Mathematics. According
- to the New York Times the new proof has been vetted by four
- researchers already, who have found no mistake.
-
- In summary:
-
- Both manuscripts have been accepted for publication, according to
- Taylor. Hundreds of people have a preprint. Faltings has simplified
- the argument already. Diamond has generalised it. People can read it.
- The immensely complicated geometry has mostly been replaced by simpler
- algebra. The proof is now generally accepted. There was a gap in this
- second proof as well, but it has been filled since October.
