OpenAI reports Smith–Toda complexes at every height with varying primes

For every nonnegative height n, there is some prime p and a finite p-local spectrum whose Brown–Peterson homology is BP∗/(p,v₁,…,vₙ) with its canonical comodule structure and degree-zero generator.

Sources for this record

What was already known

Smith–Toda complexes were known at selected heights and primes, while existence at every height remained open. The manuscript uses a prime that may vary with the requested height.

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 Notable

Gives all-height Smith–Toda existence in ordinary finite p-local spectra when the prime may depend on height.

Limitations

It does not give one prime valid at every height, an explicit bound on p, or a multiplication on the final spectrum.

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.
