What was already known
Host and Kra proved L² convergence for arbitrary systems, and Bourgain proved pointwise double recurrence; higher-length pointwise results required additional structural assumptions in the manuscript’s account.
AI involvement
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
Establishes almost-everywhere convergence for all finite lengths under ordinary mixing alone.
Limitations
The tuple of bounded functions is fixed, so no common exceptional set for all function tuples is asserted; no rate of mixing or convergence is claimed. No completed proof check was documented in the available sources.
Technical verification
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 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.
Correction and publication history
Primary manuscript, attribution, and prior-work review for non-notifying local inclusion; technical check remains undocumented.
