What was discovered

A conjecture that every elliptic curve over the rationals is modular. Its partial proof by Wiles established Fermat's Last Theorem.

Formulated at the Tokyo-Nikkō symposium (1955) and refined by Shimura; Weil helped spread it, so it is sometimes called the Shimura-Taniyama-Weil conjecture.

What it led to

  • the proof of Fermat's Last Theorem (1994)
  • the modularity theorem (2001)
  • the Langlands programme
