OpenAI reports a positive finite Hausdorff gauge for SLE traces

For every fixed 0<κ<8, there is a deterministic Hausdorff gauge that almost surely gives positive finite measure to every nontrivial compact positive-time segment of ordinary chordal SLE_κ.

Sources for this record

What was already known

Beffara identified the trace dimension, Rezaei showed the critical power gauge gives zero measure, and Schramm asked whether a deterministic gauge could give a sigma-finite trace measure.

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

Answers Schramm’s Hausdorff-measure existence question for chordal SLE with 0<κ<8.

Limitations

The manuscript constructs a gauge via deterministic moment integrals. The Lean scope checks positivity for a later explicit gauge, but not finiteness for every segment or the first manuscript’s moment-integral construction.

Technical verification Partial

OpenAI reports a Lean check of a narrower theorem, case, or component; the selected claim extends beyond that scope.

Formal checking

The pinned OpenAI Lean scope note verifies only this narrower statement, not the full selected claim.

Scope
For 0<κ<8, the explicit gauge r^d(log log(1/r))^{(2-d)/2}, d=1+κ/8, gives positive measure to every nontrivial compact positive-time chordal SLE_κ segment.

Evidence source

Checking a formal statement does not establish that it matches the original problem.

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.
