OpenAI reports critical honeycomb polygon diameter-tail exponents

At the critical honeycomb self-avoiding-walk activity, the total weight of unrooted polygons of diameter at least r is r^{-2+o(1)}, their length-weighted tail is r^{-2/3+o(1)}, and the truncated second-length-moment mass through diameter r is at most r^{2/3+o(1)}.

Sources for this record

What was already known

The honeycomb connective constant was established, while the predicted three-quarter spatial exponent and corresponding critical polygon length-diameter relations had not been proved by that result.

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

Establishes the critical polygon tail laws that yield diameter n^{3/4+o(1)} under length-cutoff ensembles.

Limitations

Polygons are counted modulo translations at the critical activity; the tail statements differ from fixed-exact-length walk claims. The linked Lean scope checks finite bridge measures and other supporting honeycomb estimates, not these polygon diameter tails.

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.
