Advancing Mathematics Research with AI-Driven Formal Proof Search
This presentation explores AlphaProof Nexus, a groundbreaking AI agent that autonomously solves open mathematical problems by generating formal proofs in Lean. We examine how modular agentic architectures combining large language models with compiler-based verification solved 9 longstanding Erdős problems—including two that remained open for 56 years—and delivered practical breakthroughs in algebraic geometry, graph theory, and optimization. The talk reveals how this paradigm shift from specialized systems to simple agentic loops is democratizing machine-verified mathematical discovery.Script
Two Erdős problems remained unsolved for 56 years until an AI agent proved them correct in Lean, with every logical step verified by a compiler. This is AlphaProof Nexus, where artificial intelligence meets the rigorous demands of research-level mathematics.
Large language models hallucinate constantly when writing mathematical proofs in natural language, making human review exhausting and error-prone. The authors bypass this entirely by generating formal proofs in Lean, where a compiler provides objective correctness guarantees with zero ambiguity.
AlphaProof Nexus operates through a modular loop where Gemini generates proof attempts, Lean validates them, and evolutionary search coordinates populations of proof sketches. Advanced configurations add Elo-rated subagents that rank plausibility and novelty, while AlphaProof itself is invoked as a specialized tool for stubborn subgoals that resist general exploration.
The agent solved 9 out of 353 open Erdős problems, including problems 125 and 138 that had defeated mathematicians for over half a century. It also proved 44 previously unsolved conjectures from the OEIS corpus, with every solution validated against formal repositories and published on Terence Tao's wiki.
Even the simplest agent architecture—just language model generation plus Lean verification, no evolutionary coordination—solved all 9 primary Erdős problems, though at higher inference cost. This reveals a surprising truth: as language models improve, the marginal benefit of complex agentic machinery is shrinking for tractable problems, while full-featured systems still deliver 2 to 5 times cost reduction on the hardest cases.
AlphaProof Nexus has moved beyond benchmarks into live research collaboration, discovering exact convergence rates for Anchored GDA, resolving graph theory conjectures, and ending a 15 year open question in algebraic geometry.
