OpenAI reports the planar Schrödinger convergence endpoint

For initial data in H^(1/3)(R^2), the planar Schrödinger evolution converges almost everywhere to the data as positive time tends to zero, with the pointwise evolution defined by a Gaussian regularization limit first.

What was already known

Bourgain’s counterexample requires Sobolev regularity s >= 1/3 in the plane. Du, Guth, and Li proved convergence for s > 1/3, leaving equality open (manuscript introduction, History and significance, pp. 2–3).

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

Settles the sharp planar Sobolev endpoint of Carleson’s Schrödinger convergence problem.

Limitations

The theorem specifies Gaussian regularization before the time limit and does not assert the stronger endpoint local L3 maximal estimate.

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.
