AI and the formalisation of mathematics

2 PM, 9 Mar 2026

Kevin Buzzard opens AIMS with his views on what a new era of formalised maths, Lean and AI—verified proofs mean for the future of research.

This first talk in the AI for Mathematical Sciences seminar series (AIMS) features Prof. Kevin Buzzard, who presents the rapid rise of formalised mathematics in computer theorem provers such as Lean. Over the past decade, mathematicians have begun encoding proofs in precise formal languages that machines can verify line by line, eliminating ambiguity and ensuring complete logical rigour. In these systems, proofs can be checked automatically, helping to create durable, searchable libraries of trusted results and transforming how mathematicians collaborate and build on one another’s work.

Prof. Buzzard discusses the motivations of this movement, the technical bottlenecks that remain, and the growing role of AI tools that can write Lean code and help verify the output of large language models. He also reflects on leading a major project to formalise a 21st-century proof of Fermat’s Last Theorem, and what such ambitious efforts signal for the future of mathematical research.
