Full support of the zero-temperature Sherrington-Kirkpatrick order parameter

OpenAI

The September manuscript proves that every admissible integrable zero-temperature Parisi minimizer for the pure zero-field Sherrington–Kirkpatrick model, with covariance ξ(t)=t²/2, has full relative Stieltjes support on [0,1). It uses a rational coercive identity and strict curvature on constant intervals.

What was already known

Chen’s July 2026 ChatGPT-generated paper already proved this full-support theorem by a different transformed-density route; earlier work established infinitely many support points without excluding gaps.

AI involvement AI-led

OpenAI attributes the September manuscript to its internal model. No named human mathematical origin or check of this separate proof is documented.

The repository directly attributes the manuscript to an internal model; autonomy from task selection and guidance is not documented.

Importance Notable

The contribution is a distinct explicit proof method for an existing full-support theorem.

Limitations

The published Lean library states the conditional zero-field theorem; the comparator challenge is only a template. No named human explanation, independent build replay or axiom audit is documented.

Technical verification Formal (Lean 4 (source-reported))

OpenAI publishes a Lean 4 proof of the selected full-support statement in OAI/Probability/SKSupport/Main.lean, and its scope note matches the conditional zero-field claim. The comparator challenge intentionally contains sorry and is only a statement template; the completed proof is the library theorem. Build and axiom dependencies were not reproduced here.
