OpenAI reports the rational-homology form of Quillen’s conjecture

For every finite group G and prime p with trivial largest normal p-subgroup, the poset of nontrivial elementary abelian p-subgroups of G has nonzero augmented reduced rational homology.

What was already known

Quillen’s conjecture had been reduced through major families of finite groups, with remaining cases requiring additional chain-level cycles and propagation. The full all-group, all-prime rational-homology form remained open.

AI involvement AI-led

OpenAI credits itself as manuscript author and states that its internal frontier model produced the results in this release. Individual human input is not detailed enough to establish task-only autonomy.

OpenAI is named as author on the manuscript, and its release attributes the results to an internal frontier model. The individual human input is not detailed enough to establish autonomy.

Importance Major

Establishes the stronger rational-homology form of Quillen’s conjecture for every finite group and prime.

Limitations

The hypothesis is O_p(G)=1; the conclusion concerns the rational homology of the elementary-abelian subgroup poset.

Technical verification Reported

Reported is the default when evidence for a higher level is insufficient. The OpenAI-authored manuscript reports and argues the result, but the reviewed sources do not document a completed check of the full assessed claim.

Human understanding Few

Few is the default when evidence for a higher level is insufficient. No named person is documented as explaining the central argument for this assessed contribution.
