OpenAI claim summary for Phys-29

Summary of a claim published in openai/math; not a claim by this platform.
For one nucleus the theorem states that adding an electron cannot lower the energy once n>Z+C, with one universal C for every real Z>=1. It therefore bounds N0(Z)-Z uniformly, strengthening the problem statement asymptotic assertion and also treating multiple nuclei. The claimed conclusion supplies the requested case and extends it in the directions just specified.
Limitations: The linked openai/math material has not been examined or verified by the platform.

Bounded Excess Electrons
OpenAI's claim
OpenAI presents a proof in the selected manuscript. Coulomb molecules are claimed to bind at most $Z+CM$ electrons, and neutral atoms to have universally bounded first ionization energy and half-electron exterior radius.Mathematical statement of the claimed result
Result 1.
For $M$ fixed nuclei at distinct positions $R_j\in\mathbb R^3$, charges $z_j\ge1$, and total $Z=\sum_jz_j$, use the antisymmetric spin-two electron Hamiltonian \[ H_n=\sum_{i=1}^n\left(-\tfrac12\Delta_i-\sum_j\frac{z_j}{|x_i-R_j|}\right) +\sum_{i<j}\frac1{|x_i-x_j|},\qquad E_n=\inf\sigma(H_n),\quad E_0=0. \] The claimed constant $C<\infty$ is universal over charges and positions, and obeys \[ E_n<E_{n-1}\quad\Longrightarrow\quad n\le Z+CM, \qquad n>Z+CM\quad\Longrightarrow\quad E_n=E_{n-1}. \] For a single nucleus the strict-binding bound becomes $n\le Z+C$, including real $Z\ge1$.Outline of the argument
Ground states are compared across particle sectors using common localization and screening fields. Local count bounds, changes of observation law, and estimates in nuclear voids control excess particles; deterministic comparison fields give both sides of the neutral-atom energy and radius bounds.Formal verification
For family 263, the documented entries give the large-$m$ ionization-energy coefficient and the generalized neutral outer-radius asymptotics. Fixed-$m$ limits and the general uniform excess-charge manuscript are not selected. No Comparator is assigned to the selected manuscript here; the family page selects other papers or supporting statements. This site has not executed the Lean code. The scope descriptions do not certify the remaining manuscript arguments.Status caveat
OpenAI attributes these manuscripts to work by an internal model. Its release cautions that arguments without formalization can contain mistakes. This catalogue has not independently checked the proofs; the labels report the mathematical claims attributed to OpenAI.Sources
