Exact Hausdorff gauges for SLE

OpenAI research collection · 2 manuscripts · Source checked 2026-10-19

OpenAI's result summary

Resolves Schramm’s Hausdorff-measure question for chordal SLE_(κ), 0< \kappa< 8. The explicit gauge r^d(loglog(1/r))^{(2-d)/2}, d=1+\kappa/8, gives almost surely positive finite measure to every trace segment \gamma([s,t]) with 0< s< t< ∞, and finite expected measure to the trace in every bounded disk.

An exact Hausdorff gauge for SLE

For each 0< \kappa< 8, we construct a deterministic Hausdorff gauge that almost surely assigns positive finite measure to every nontrivial compact positive-time segment of chordal Schramm–Loewner evolution. This answers Schramm's Hausdorff-measure existence problem in this parameter range. The entire trace has finite expected…

For each 0< \kappa< 8, we construct a deterministic Hausdorff gauge that almost surely assigns positive finite measure to every nontrivial compact positive-time segment of chordal Schramm–Loewner evolution. This answers Schramm's Hausdorff-measure existence problem in this parameter range. The entire trace has finite expected gauge measure in each bounded box.

An explicit exact Hausdorff gauge for SLE

For each fixed 0< \kappa< 8, let d=1+\kappa/8. The gauge h(r)=r^d(loglog(1/r))^{(2-d)/2} at sufficiently small radii almost surely gives positive finite Hausdorff measure to every nontrivial positive-time compact segment of chordal SLE_(κ). This gives an explicit solution to Schramm's Hausdorff-measure problem in this parameter…

The gauge h(r)=r^d(loglog(1/r))^{(2-d)/2} at sufficiently small radii almost surely gives positive finite Hausdorff measure to every nontrivial positive-time compact segment of chordal SLE_(κ). This gives an explicit solution to Schramm's Hausdorff-measure problem in this parameter range. The entire trace has finite expected measure in every bounded disk. The exponent-one iterated-logarithm gauge suggested by Schramm is not sigma-finite on any such segment.

One signal in the wider AGI picture

New mathematical reasoning could help AI tackle harder scientific and computational problems. How reliably these skills transfer beyond mathematics will determine how much they contribute to general intelligence.
