Not evaluated
Endpoint regularity of the planar centered maximal function (family 085)
The gist
On October 6, 2026, OpenAI announced, from an unreleased internal model, a manuscript on an endpoint gradient bound for the centred disk maximal operator.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.
AI draft, not reviewedWhat has not been reviewed?

What it changes
If the manuscript were correct, it would provide, going by its title, a bound on the gradient (the rate of variation) of the centred disk maximal operator, in an endpoint case. The repository files this family under the section “Real and complex analysis”.
What remains unclear
No check of the Lean supplied by OpenAI (a language in which a computer checks every step of a proof) by a third party, nor any other independent assessment, is recorded. The sources read do not detail how much of the manuscript the Lean covers.

Method
The manuscript in the openai/math repository is titled “An Endpoint Gradient Bound for the Centered Disk Maximal Operator” and is dated September 26, 2026. OpenAI supplies lean/docs/085.md and two Lean files (two Comparator statements), lean/ComparatorChallenges/DiskMaximal.lean and lean/ComparatorChallenges/SignedFiniteBand.lean; formalization.yaml carries “review: status: unchecked” and lists the family in its sources. history.md reports no revision of the manuscript. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
