OpenAI reports canonical ampleness for compact hyperbolic Kähler manifolds

Every positive-dimensional compact connected Kähler manifold with no nonconstant holomorphic map from the complex line has ample canonical bundle and is projective.

Sources for this record

What was already known

Canonical ampleness was known under stronger negative or quasi-negative holomorphic sectional curvature assumptions, and under Kähler hyperbolicity. Those metric hypotheses are distinct from the absence of entire curves (manuscript introduction, pp. 1–2).

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

Resolves Kobayashi’s canonical-ampleness conjecture in the smooth compact Kähler category.

Limitations

The statement is for compact connected Kähler manifolds; it does not cover singular or noncompact spaces.

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.
