1/30/2024 0 Comments Theorems in latexitThe full proof that the two problems were closely linked was accomplished in 1986 by Ken Ribet, building on a partial proof by Jean-Pierre Serre, who proved all but one part known as the "epsilon conjecture" (see: Ribet's Theorem and Frey curve). An outline suggesting this could be proved was given by Frey. In 1984, Gerhard Frey noticed an apparent link between these two previously unrelated and unsolved problems. It was widely seen as significant and important in its own right, but was (like Fermat's theorem) widely considered completely inaccessible to proof. Known at the time as the Taniyama–Shimura conjecture (eventually as the modularity theorem), it stood on its own, with no apparent connection to Fermat's Last Theorem. Separately, around 1955, Japanese mathematicians Goro Shimura and Yutaka Taniyama suspected a link might exist between elliptic curves and modular forms, two completely different areas of mathematics. Building on Kummer's work and using sophisticated computer studies, other mathematicians were able to extend the proof to cover all prime exponents up to four million, but a proof for all exponents was inaccessible (meaning that mathematicians generally considered a proof impossible, exceedingly difficult, or unachievable with current knowledge). In the mid-19th century, Ernst Kummer extended this and proved the theorem for all regular primes, leaving irregular primes to be analyzed individually. Over the next two centuries (1637–1839), the conjecture was proved for only the primes 3, 5, and 7, although Sophie Germain innovated and proved an approach that was relevant to an entire class of primes. The special case n = 4, proved by Fermat himself, is sufficient to establish that if the theorem is false for some exponent n that is not a prime number, it must also be false for some smaller n, so only prime values of n need further investigation.

This section needs additional citations for verification. Attempts to prove it prompted substantial development in number theory, and over time Fermat's Last Theorem gained prominence as an unsolved problem in mathematics. The claim eventually became one of the most notable unsolved problems of mathematics. This claim, which came to be known as Fermat's Last Theorem, stood unsolved for the next three and a half centuries. His claim was discovered some 30 years later, after his death. ![]() Although he claimed to have a general proof of his conjecture, Fermat left no details of his proof, and no proof by him has ever been found. Around 1637, Fermat wrote in the margin of a book that the more general equation a n + b n = c n had no solutions in positive integers if n is an integer greater than 2. The Pythagorean equation, x 2 + y 2 = z 2, has an infinite number of positive integer solutions for x, y, and z these solutions are known as Pythagorean triples (with the simplest example 3,4,5). ![]() It is among the most notable theorems in the history of mathematics and prior to its proof was in the Guinness Book of World Records as the "most difficult mathematical problem", in part because the theorem has the largest number of unsuccessful proofs. The unsolved problem stimulated the development of algebraic number theory in the 19th and 20th centuries. It also proved much of the Taniyama–Shimura conjecture, subsequently known as the modularity theorem, and opened up entire new approaches to numerous other problems and mathematically powerful modularity lifting techniques. It was described as a "stunning advance" in the citation for Wiles's Abel Prize award in 2016. ![]() After 358 years of effort by mathematicians, the first successful proof was released in 1994 by Andrew Wiles and formally published in 1995. Consequently the proposition became known as a conjecture rather than a theorem. Although other statements claimed by Fermat without proof were subsequently proven by others and credited as theorems of Fermat (for example, Fermat's theorem on sums of two squares), Fermat's Last Theorem resisted proof, leading to doubt that Fermat ever had a correct proof. Fermat added that he had a proof that was too large to fit in the margin. ![]() The proposition was first stated as a theorem by Pierre de Fermat around 1637 in the margin of a copy of Arithmetica. The cases n = 1 and n = 2 have been known since antiquity to have infinitely many solutions. In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c satisfy the equation a n + b n = c n for any integer value of n greater than 2.
