Proving Fermat's TheoremDate: 22 Jun 1995 00:15:01 -0400 From: Dionisio Laeber Fleitas Subject: Fermat's Last Theorem Has Fermat's Last Theorem already been proved ? If so, send me the idea of the proof, please. Date: 22 Jun 1995 09:13:31 -0400 From: Dr. Ken Subject: Re: Fermat's last theorem Hello there! Yes, most people accept that Fermat's Last Theorem has been proven. I say "most" because there are only a handful of people in the world who can even understand the whole proof (it's huge!), so it's hard to say whether all steps are completely rigorous. The general feeling is that the proof is complete. Here's something that was in the Frequently Asked Questions file for the newsgroup sci.math: http://daisy.uwaterloo.ca/~alopez-o/math-faq/node1.html Fermat's Last Theorem History of Fermat's Last Theorem *What is the current status of FLT? Wiles' line of attack If not, then what? Did Fermat prove this theorem? *What is the current status of FLT? 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.
