Not evaluated
The ℓ¹-Bass and complex Bass trace conjectures (family 207)
The gist
On October 6, 2026, OpenAI announced 2 manuscripts: one on the ℓ^1-Bass conjecture for discrete groups, the other on the Bass trace conjecture.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.

What it changes
If the result held, it would concern two conjectures linked to the name Bass: one for discrete groups, the other for complex group rings. The second manuscript also deals with the characteristic-zero Kaplansky idempotent conjecture.
What remains unclear
The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI alone, and formalization.yaml marks it “unchecked”. No third-party evaluation is read, and the sources do not give the exact statement each manuscript claims to prove.

The result is declared neither right nor wrong.
To move to “Under review”: a public review under way. To “Peer reviewed”: a journal publication or a review by named experts.

Method
2 manuscripts: “The ℓ^1-Bass Conjecture for Discrete Groups” (October 5, 2026) and “The Bass trace conjecture and the characteristic-zero Kaplansky idempotent conjecture” (September 24, 2026). Lean supplied by OpenAI: 2 Comparator statements (BassTorsionFree.lean, BassTrace.lean), described in lean/docs/207.md; family present in the “sources” of formalization.yaml. 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.
