D <=> A

D : Diaphantine equations
eg.
$x^{n} + y^{n} = z^{n}$

A = Automorphic Form (eg. Elliptic Curves used in highest Cryptography “ECC” )

Fermat’s Last Theorem: after failures of 350 yrs, Andrew Wiles in 1994 proved easier from reversed direction A to D.

Lycée Pierre de Fermat (Maths Supérieures & Spéciales @Toulouse, France) was my Alma mater。

Use Fermat’s Last Theorem to prove irrational of cubic root of 2.

Why the Proof of Fermat’s Last Theorem Doesn’t Need to Be Enhanced

Summary:

Andrew Wiles’ Proof of Fermat’s Last Theorem (FLT) by contradiction :

A. Assume FLT is true for all prime p (Why? sufficient to prove only for prime) such that:

$a^p + b^p = c^p$

B. then a, b, c could be rearranged into an Elliptic Curve,

C. then leverage such Elliptic Curve into a Galois Represebtation.

D. then a Modular Form.

E. then leads to an impossible weight 2 level 2 Modular Form.

Hence,

¬E -> ¬D -> ¬C -> ¬B -> ¬A (proved)

1950s Taniyama-Shimura-Weil proved the link below:

B -> (via assume C) -> D

Andrew Wiles’ took 7 years to complete the whole proof in 1994 by proving the missing link C -> D.

Assume

$\sqrt [3] 2$ is rational, then

$\displaystyle \sqrt [3] 2 = \frac {q}{p} \,$ with p, q integers

After arrangement, we get

$p^3 + p^3 = q^3$ … [*]

According to Fermat’s Last Theorem, the equation [*] has no solution.

Hence, par absurd,

$\sqrt [3] 2$ is IRrational.

I am a fan of Fermat, not only because my university Alma Mater was in his hometown Toulouse (France) named after him “Lycée Pierre de Fermat (Classe Préparatoire Aux Grandes Ecoles) ” , but also the “Fermat’s Last Theorem” (FLT) has fascinated for 350 years all great Mathematicians including Euler, Gauss,… until 1993 finally proved by the Cambridge Professor Andrew Wiles. Another “Fermat’s Little Theorem” is applied in computer Cryptography .
