Andrew Wiles’s proof of Fermat’s Last Theorem (FLT) was not an isolated achievement—it interwove several deep mathematical ideas. In resolving FLT, mathematicians relied on related theorems, notably:

1. The Modularity Theorem (formerly the Taniyama–Shimura–Weil Conjecture): This result links elliptic curves with modular forms. Wiles’s work showed that a certain class of elliptic curves is modular, a connection that was critical in proving FLT.

2. Ribet’s Theorem: Serving as a bridge, Ribet demonstrated that the truth of the modularity theorem for semi-stable elliptic curves would imply FLT. Essentially, he connected a conjecture about elliptic curves with the long-standing problem in number theory.

3. Additional Insights: Subsequent work—such as advances related to the Sato–Tate Conjecture—continues to reveal how patterns in number theory and analysis inform each other. These unifications illustrate that resolving one conjecture often illuminates many others.

Philosophically, these interconnected resolutions embody the unity and beauty of mathematics. They show that diverse areas of inquiry, when integrated, can provide profound insights into seemingly isolated problems.
