OpenAI research collection · 1 manuscript · Source checked 2026-10-19

OpenAI's result summary

Proves Bloch's conjecture: for every smooth connected projective complex surface S with p_g(S)=0, the Albanese map CH_0(S)^0\toAlb(S)(\mathbb C) on integral degree-zero zero-cycles is an isomorphism. This combines the new p_g=q=0 theorem with the classical theorem of Bloch, Kas, and Lieberman.

Bloch’s conjecture for surfaces with p_g=0

We prove Bloch's conjecture for smooth connected projective complex surfaces with p_g=0: the Albanese homomorphism on integral degree-zero zero-cycles is an isomorphism.

One signal in the wider AGI picture

New mathematical reasoning could help AI tackle harder scientific and computational problems. How reliably these skills transfer beyond mathematics will determine how much they contribute to general intelligence.
