Understanding Fermat’s Last Theorem
The Historical Background
Fermat’s Last Theorem, originally conjectured by Pierre de Fermat in 1637, states that:
> There are no three positive integers \(a\), \(b\), and \(c\) that satisfy the equation \(a^n + b^n = c^n\) for any integer value of \(n\) greater than 2.
Fermat famously noted in the margin of his copy of Diophantus's "Arithmetica" that he had a marvelous proof for this proposition, but the margin was too narrow to contain it. Over the centuries, the theorem remained unproven, despite numerous partial proofs and significant advances in related areas of mathematics.
Importance and Challenges
Fermat’s Last Theorem is significant because it touches upon fundamental concepts in number theory, algebra, and mathematical logic. Its proof required innovative techniques and the development of new mathematical tools, as earlier methods failed to resolve the problem for all integers \(n > 2\).
The challenge was compounded by the theorem’s non-constructive nature and its resistance to classical methods. As a result, it became a central problem that motivated the advancement of algebraic number theory, modular forms, and elliptic curves.
Andrew Wiles and the Breakthrough
The Journey to the Proof
Andrew Wiles, a British mathematician, dedicated several years to studying Fermat’s Last Theorem. His approach was to link the theorem to the Taniyama-Shimura-Weil conjecture (now known as the Modularity Theorem), which posited a deep connection between elliptic curves and modular forms.
By proving a special case of this conjecture for semistable elliptic curves, Wiles indirectly proved Fermat’s Last Theorem. This strategy was inspired by earlier work by Gerhard Frey, Ken Ribet, and others, who identified the critical connection between the two problems.
The Publication of Wiles’s Proof
Wiles first announced his proof in 1993 during a lecture at the Isaac Newton Institute. However, an error was discovered, which temporarily cast doubt on the validity of the proof. Wiles, alongside his collaborator Richard Taylor, subsequently fixed the error, leading to a complete and rigorous proof published in 1995.
The final, corrected proof is detailed in Wiles’s paper titled "Modular elliptic curves and Fermat’s Last Theorem" published in the Annals of Mathematics.
