OpenAI reports equivariant Hikita for arbitrary quivers

For every finite quiver, including loops and multiple arrows, and every regular stability character with stable semistable locus and free gauge action, the equivariant cohomology algebra of its Nakajima variety is canonically isomorphic to the coordinate ring of the scheme-theoretic stability-cocharacter fixed locus on the flavor-deformed Coulomb branch.

Sources for this record

What was already known

Hikita established fixed-scheme cohomology comparisons in Hilbert-scheme and related type-A examples. Subsequent quiver results covered restricted finite types and framing conditions; the manuscript notes that an earlier unrestricted ADE assertion requires qualification (manuscript introduction, History and the comparison problem, pp. 2–3).

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

Proves the cohomological Hikita identification across all finite quivers under the stated regularity hypothesis.

Limitations

The result requires regular stability, works with the full scheme-theoretic fixed locus, and does not assert the quantized Hikita statement or cover arbitrary reductive gauge groups.

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.
