OpenAI reports Bloch’s conjecture for complex surfaces with pg = 0

For every smooth connected projective complex surface with geometric genus pg = 0, the Albanese map on integral degree-zero zero-cycles is an isomorphism. In the remaining general-type case pg = q = 0, this says the degree map CH0(S) to Z is an isomorphism.

What was already known

Bloch–Kas–Lieberman proved the integral assertion for surfaces outside general type. The remaining general-type problem concerns pg = q = 0, while earlier results handled particular constructions and quotient geometries (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 Bloch’s zero-cycle conjecture for all smooth projective complex surfaces with pg = 0.

Limitations

The claim concerns smooth connected projective complex surfaces and integral zero-cycles; the main new case is general type with pg = q = 0.

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.
