Ten Digits on a Train: AI-Assisted Verification of Two Eigenvalue Problems
Summary
This article reports on a human-AI collaboration focused on verifying accurate numerical eigenvalues, particularly in singular or non-normal mathematical contexts. Two specific computations are detailed: first, for a singular self-adjoint Schrödinger operator, a verified zero count and Dirichlet-Neumann bracketing certified the complete negative spectrum to ten decimal places. Second, for a delicate non-normal atom-molecule benchmark, a previously unresolved resonance pair was separated, with each member enclosed to ten digits. This second achievement involved reformulating the problem as a global matching system for projective solution lines, encoding the infinite tail as uncertainty, and employing a componentwise, tail-robust Krawczyk-Brouwer inclusion for certification. The work also exposed AI's strengths in generating candidates and strategies, alongside its limitations, as several AI-produced proofs failed due to overlooked critical checks, underscoring the continued necessity of human mathematical judgment.
Key takeaway
For research scientists developing AI-assisted mathematical verification systems, you must integrate robust human oversight into your proof certification workflows. While AI can rapidly generate candidate solutions and plausible strategies, its outputs require stringent, componentwise checks to avoid subtle errors, as demonstrated by failed tail arguments. Prioritize building systems where the "proof object" is paramount, ensuring human mathematical judgment remains decisive for critical validations.
