Formalizing Fermat's Last Theorem in Lean: A Collaborative Open Source Project
2025-08-21
An international collaboration led by Kevin Buzzard is undertaking the ambitious task of formally proving Fermat's Last Theorem using the Lean theorem prover. Funded by the UK's Engineering and Physical Sciences Research Council and hosted at Imperial College London, this project pushes the boundaries of mathematical proof verification. By using a computer to verify the proof, the project explores the potential of formalization and automated verification in mathematics, with implications for future research.
