New Riemann Hypothesis Proof Formalized in Lean by AxiomProver Within Hours

Research on the Riemann Hypothesis saw notable progress: it has now been shown that over 67% of the zeros of the Riemann zeta function lie on the critical line and are simple. Number theorist Youness Lamzouri posted a short, elegant new proof of this result on arXiv, and Axiom's AxiomProver formalized the proof with the Lean theorem prover within hours, with the formalization included in the paper's appendix.

Confirmed

• The new result shows that over 67% of zeta zeros lie on the critical line and are simple, previously making headlines in connection with Anthropic-related work.
• Youness Lamzouri published the new proof on arXiv.
• AxiomProver fully formalized the proof and it appears in the paper's appendix; per @lawrennd, Ken Ono said the team used Lean for the formalization.
• Multiple reposts indicate the formalization was completed within hours.

Why it matters

• Rapidly formalizing frontier number theory results can boost paper credibility and shorten peer verification cycles.
• The episode demonstrates the practicality of AI theorem-proving tools like AxiomProver in real mathematical research workflows, a landmark case of AI-assisted mathematics.
