OpenAI reports joint metric and connection recovery from one boundary patch

For a compact connected smooth manifold of dimension at least three with smooth boundary and any nonempty open boundary patch, equality of zero-frequency same-patch boundary measurements for two smooth metrics and smooth unitary connections on the trivial rank-two Hermitian bundle implies they differ only by a patch-fixing diffeomorphism and a patch-identity unitary gauge.

What was already known

Earlier work recovered connections when the smooth metric was fixed, and jointly recovered geometry and connections in real-analytic settings. The arbitrary smooth joint problem with both data and observations on one patch remained open.

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

Gives simultaneous smooth uniqueness for geometry and a rank-two unitary connection from one local boundary measurement operator.

Limitations

The ambiguity is exactly a patch-fixing diffeomorphism and unitary gauge; the theorem does not claim recovery of a unique coordinate or gauge representative. The linked Lean note checks a separate bounded-measurable scalar-conductivity nonuniqueness result.

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.
