Article: # Fermat's Last Theorem: The Story of a Riddle that Confounded the World's Greatest Minds for 358 Years Fermat's last theorem is one of the most famous and intriguing problems in mathematics. It states that there are no positive integer solutions to the equation $x^n + y^n = z^n$ for any integer $n$ greater than 2. In other words, it is impossible to find three whole numbers that satisfy this equation when the exponent is higher than 2. For example, $3^2 + 4^2 = 5^2$ is a valid solution when $n = 2$, but there is no such solution when $n = 3$ or higher. The theorem is named after Pierre de Fermat, a 17th-century French lawyer and amateur mathematician who claimed to have a proof of it but never wrote it down. He scribbled a note in the margin of his copy of Arithmetica, a book by the ancient Greek mathematician Diophantus, saying that he had "a truly marvelous proof" of the theorem but that "the margin is too narrow to contain it". This mysterious note sparked centuries of curiosity and frustration among mathematicians who tried to find Fermat's proof or come up with their own. Many brilliant minds contributed to the quest for proving Fermat's last theorem, but none succeeded until 1995, when Andrew Wiles, a British mathematician at Princeton University, published a monumental proof that spanned over 100 pages and used sophisticated techniques from modern mathematics. Wiles had been fascinated by Fermat's last theorem since he was a 10-year-old boy and devoted seven years of his life to working on it in secrecy. His proof was hailed as one of the greatest achievements of mathematics and earned him numerous awards and honors. In this article, we will explore the story of Fermat's last theorem and its proof, from its origin in ancient Greece to its resolution in modern times. We will see how this simple statement with a complex history captivated generations of mathematicians and challenged their creativity and ingenuity. We will also see how this story illustrates the beauty, the mystery, and the joy of mathematics. ## Fermat's Last Theorem: A Simple Statement with a Complex History Fermat's last theorem is not really a theorem, but a conjecture, a statement that has not been proven. Fermat himself never published his proof, and it is widely believed that he did not have one, or that his proof was flawed or incomplete. However, he did prove some special cases of the theorem, such as when $n = 4$ or when $n$ is a prime number. He also proved some related results, such as the fact that every prime number of the form $4k + 1$ can be written as the sum of two squares. Fermat was not the first to study the equation $x^n + y^n = z^n$. In fact, he was inspired by Diophantus, who lived in Alexandria in the 3rd century AD and wrote a series of books called Arithmetica, which dealt with solving equations involving rational numbers (fractions). Diophantus was interested in finding rational solutions to the equation, not integer solutions. For example, he showed that $x^2 + y^2 = z^2$ has infinitely many rational solutions of the form $x = \fracm^2 - n^2m^2 + n^2$, $y = \frac2mnm^2 + n^2$, and $z = \fracm^2 + n^2m^2 + n^2$, where $m$ and $n$ are any rational numbers. He also considered some cases of the equation when $n = 3$ or $n = 4$, but did not find any rational solutions. Diophantus's work was largely forgotten until the 16th century, when it was rediscovered by European mathematicians. Among them was Pierre de Fermat, who lived in Toulouse and worked as a lawyer and a magistrate. Fermat was also a passionate mathematician who corresponded with other scholars and made many discoveries in number theory, geometry, calculus, and probability. He often posed problems and challenges to his friends and colleagues, but rarely revealed his methods or proofs. He wrote most of his mathematical notes in the margins of his books, which were only published after his death in 1665. One of these notes was his famous claim to have a proof of what is now known as Fermat's last theorem. He wrote it in his copy of Diophantus's Arithmetica, next to a problem that asked to find a right-angled triangle whose area is a square number. Fermat observed that this problem is equivalent to finding integer solutions to the equation $x^4 + y^4 = z^4$, which he said was impossible. He then generalized this statement to any exponent greater than 2 and wrote: "It is impossible to separate a cube into two cubes, or a fourth power into two fourth powers, or in general, any power higher than the second into two like powers. I have discovered a truly marvelous proof of this, which this margin is too narrow to contain." This tantalizing note sparked centuries of curiosity and frustration among mathematicians who tried to find Fermat's proof or come up with their own. Many attempts were made to prove or disprove the theorem, but none succeeded in covering all possible cases. Some mathematicians proved the theorem for specific values of $n$, such as when $n = 5$, $n = 7$, or $n = 11$. Others proved the theorem for infinitely many values of $n$, such as when $n$ is a regular prime (a prime number that satisfies a certain condition) or when $n$ is divisible by 4. However, these results left many gaps and exceptions that could not be resolved by existing methods. Along the way, many interesting and important results were discovered in number theory and related fields. For example, Euler proved that every even perfect number (a number that is equal to the sum of its proper divisors) is of the form $2^p-1(2^p - 1)$, where $p$ is a prime number and $2^p - 1$ is also a prime number (called a Mersenne prime). Sophie Germain proved that if $p$ is an odd prime number such that $2p + 1$ is also a prime number (called a Sophie Germain prime), then Fermat's last theorem holds for $n = p$. Kummer developed the theory of ideal numbers and showed that Fermat's last theorem holds for all regular primes (a prime number that satisfies another condition). These results also had applications and implications in cryptography, coding theory, and computer science. ## Andrew Wiles: A Childhood Dream and a Mathematical Odyssey Andrew Wiles was born in 1953 in Cambridge, England. He grew up in a family of academics and developed an early interest in mathematics. When he was 10 years old, he found a copy of Eric Temple Bell's book The Last Problem at his local library and was captivated by the story of Fermat's last theorem. He decided that he would be the one to prove it and began to study number theory on his own. Wiles pursued his mathematical education at Cambridge University, where he earned his bachelor's degree in 1974 and his doctorate in 1980 under the supervision of John Coates. He then moved to the United States and became a professor at Princeton University. He worked on various topics in number theory, such as Iwasawa theory, elliptic curves, and modular forms. He also kept his interest in Fermat's last theorem alive, but did not share it with anyone. In 1986, Wiles learned about Ribet's proof of the epsilon conjecture, which showed that Fermat's last theorem would follow from the modularity conjecture for semistable elliptic curves. This gave him a new hope and a new direction for his research. He realized that he had some of the tools and ideas needed to attack the modularity conjecture, but he also knew that it was a very difficult and risky problem. He decided to work on it secretly, without telling anyone except his wife. For the next seven years, Wiles devoted himself to proving the modularity conjecture for semistable elliptic curves. He worked in his attic office at Princeton, isolated from his colleagues and students. He faced many technical difficulties and dead ends, but he also made some breakthroughs and discoveries. He used methods from algebraic geometry, such as deformation theory and Galois representations, to link elliptic curves with modular forms. He also used results from modular forms, such as the Langlands-Tunnell theorem and the Shimura-Taniyama-Weil conjecture, to construct elliptic curves with certain properties. In June 1993, Wiles felt that he had completed his proof and decided to announce it at a conference in Cambridge, England. He gave three lectures titled "Modular Forms, Elliptic Curves and Galois Representations", which attracted a large audience of mathematicians from around the world. In the third lecture, he revealed that his main result implied the modularity conjecture for semistable elliptic curves, and hence Fermat's last theorem. The audience was stunned and amazed by his achievement. Wiles received a standing ovation and became an instant celebrity. ## The Proof: A Triumph of Human Ingenuity and Collaboration Wiles's proof of Fermat's last theorem was not yet complete. He had to write it down in detail and submit it for publication in a peer-reviewed journal. He chose the Annals of Mathematics, one of the most prestigious journals in mathematics. He sent his manuscript to the editors in August 1993 and expected it to be reviewed by several experts in the field. However, in September 1993, Wiles received some bad news. One of the referees had found a serious error in his proof. There was a gap in one of his arguments involving a certain type of object called an Euler system. Wiles had assumed that such an object existed for his elliptic curves, but he had not proved it or given a reference for it. The referee pointed out that this assumption was not justified and that there was no known way to construct such an object. Wiles was devastated by this discovery. He felt that he had failed and that his life's work was ruined. He tried to fix the error by himself, but he could not find a solution. He realized that he needed help from someone who knew more about Euler systems than he did. He contacted his former student Richard Taylor, who was then a professor at Harvard University. Taylor agreed to join him in his quest to save the proof. Together, Wiles and Taylor worked on repairing the proof for almost a year. They searched for alternative ways to prove the existence of an Euler system or to avoid using it altogether. They also consulted with other experts in number theory, such as Nick Katz, Brian Conrad, Fred Diamond, Christophe Breuil, and Ken Ribet. They faced many obstacles and setbacks, but they also made some progress and improvements. Finally, in September 1994, Wiles had a breakthrough. He realized that he could use a different type of object, called a Hecke ring, to replace the Euler system. He also found a way to relate the Hecke ring to the Galois representation of his elliptic curve, using a technique called patching. He checked his calculations and convinced himself that he had solved the problem. He called Taylor and told him the good news. Wiles and Taylor revised their proof and submitted it to the Annals of Mathematics in October 1994. The new proof was divided into two papers: the first one, by Wiles alone, contained the main result and the strategy of the proof; the second one, by Wiles and Taylor, contained the technical details and the patching method. The papers were reviewed by several referees, who confirmed that the proof was correct and complete. The papers were published in May 1995, almost two years after Wiles's announcement. The proof spanned over 100 pages and used many advanced concepts and techniques from modern mathematics. It was widely regarded as one of the greatest achievements of mathematics and a milestone in human history. Wiles received worldwide recognition and acclaim for his accomplishment. He was awarded many prizes and honors, such as the Wolf Prize, the Abel Prize, the Royal Medal, and the knighthood. ## Conclusion Fermat's last theorem is more than just a mathematical problem.
