Riesz-energy, finiteness and every-density corollaries of the openai/math planar universal-optimality theorem, kernel-checked in Lean 4
Year: 2026
Type: preprint
Abstract: The openai/math release contains an AI-generated Lean 4 proof that the triangular lattice A of covolume one minimises the lower g-energy among all locally finite planar configurations of density one, for every smooth completely monotone g (theorem universal_energy_minimum; Comparator-accepted by us under the pinned toolchain). Inside that pinned environment we derive and kernel-check three named consequences, using only the axioms propext, Classical.choice and Quot.sound: (D1) for every s > 0 the Riesz potential t ↦ t-s/2 (i.e. |x-y|-s) is admissible, so the triangular lattice minimises the Riesz s-energy among all locally finite density-one configurations; (D1b) for s > 2 the lattice's Riesz s-energy (an Epstein zeta value) is finite, so D1 compares with a finite, attained minimum (for 0 < s ≤ 2 the lattice side is infinite and D1 only says E(C) = ∞); (D2) for every density ρ > 0 and every admissible g, the rescaled lattice ρ-1/2A has density ρ and minimises the g-energy among all locally finite density-ρ configurations; without the rescaling the statement is false (proved in Lean at ρ = 1/4, s = 4). The Riesz form ρs/2 Σ|a|-s ≤ E(C) is also kernel-checked. Mathematically each step is short (complete monotonicity of t-s/2, scaling), and the upstream manuscript already states informally that inverse powers are included; what is new is the kernel-checked form, a statement-fidelity audit against Cohn–Kumar–Miller–Radchenko–Viazovska's lower-energy formulation, planted negative controls, and re-verification by separate instances of the same AI model (producer ≠ verifier). Everything is conditional on the upstream theorem, which has not been peer reviewed and which, by its authors' account, does not claim the stronger per-potential form of the Cohn–Kumar conjecture. The Lean proofs, audit, verification runs and drafting were performed by the AI model Claude (Anthropic) under the author's direction; the author is responsible for the content.
