OpenAI reports the Hovey–Strickland thick-ideal classification

For every prime p and height n≥1, the dualizable K(n)-local stable-homotopy category has exactly n+2 thick tensor ideals, forming one strict chain; its Balmer spectrum has n+1 points.

What was already known

Hopkins and Smith classified thick subcategories of finite spectra. Hovey and Strickland proposed the corresponding classification for dualizable K(n)-local spectra, linked to stabilizer-invariant ideals of the Lubin–Tate deformation ring.

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 the Hovey–Strickland conjecture at every prime and positive height.

Limitations

The classification is for dualizable K(n)-local spectra and their ordinary thick tensor ideals; it is not a classification of all K(n)-local spectra.

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.
