AI-assisted proof establishes fixed Hodge Lie generation

For diag(1,1,1,−1,1,−1) and the local Hodge operator on coordinate plane 0123, fifteen orthogonal adjoint actions together with that operator generate sl(15,K) over every field of characteristic other than two. The same formal result gives dimension 224 and scalar rigidity for commuting endomorphisms, with determinant c²²⁴.

Sources for this record

What was already known

The source cites general representation-theoretic context and an earlier scalar-centroid criterion, but does not establish priority for this fixed generator theorem. Alexander’s earlier physical program motivates the operators.

AI involvement AI-led

Stephanie Alexander selected and directed the theorem. The disclosure credits Codex agents with the generation proof, integral commutator certificate and audits.

Agents constructed the retained geometric generation proof under Alexander's direction; independent AI origin of the chosen operators is not documented.

Importance Modest

Proves generation and rigidity for one specified operator system.

Limitations

The theorem assigns no physical response magnitude. No human specialist proof check or exhaustive novelty assessment is documented.

Technical verification Formal (Lean 4.31.0 kernel and Comparator; exact integral commutator certificate)

The cited record reports a sorry-free Lean 4.31.0 proof of the fixed generation-and-rigidity statement with only standard axioms and Comparator statement alignment. This is a source-reported machine check of the mathematical theorem, not of physical calibration; it was not rerun here.

Human understanding Few

Default for missing evidence of independent human explanation: the exposition describes the mechanism, but the disclosure attributes its construction and audits to agents and documents no human mathematical review.
