Which proofs need computer assistance?
Summary
At the LMS General Meeting 2026 celebrating the 50th anniversary of the Four-Colour Theorem, Kevin Buzzard explored how computer assistance in mathematics has evolved from simple brute-force computation to necessary formal verification. He argued that modern proofs—ranging from massive combinatorial case checks to hyper-complex contemporary fields like condensed mathematics—are reaching a scale and density where human refereeing alone is no longer sufficient. By utilizing interactive theorem provers like Lean, mathematicians can verify logical derivations step-by-step from base axioms, bridging the gap between human intuition and machine-certified mathematical truth while setting the stage for future AI-driven auto-formalization.
