Idea

In number theory, Ken Ribet‘s theorem is a statement about Galois representations associated with modular forms.

Jean-Pierre Serre ad Ken Ribet observed that together with assuming the Taniyama-Shimura modularity conjecture (as yet unproven at that time), Ribet’s theorem implies Fermat's last theorem. The modularity theorem was then proven by Andrew Wiles and Richard Taylor, thus often known now as Wiles' proof of Fermat's last theorem.
