Abstract
Let \Omega\subset\mathbb {R}^{n} , n\geq 3 , and let p , 1 < p < \infty , p \not = 2 , be given. In this paper we study the dimension of p -harmonic measures that arise from non-negative solutions to the p -Laplace equation, vanishing on a portion of \partial\Omega , in the setting of \delta -Reifenberg flat domains. We prove, for p \geq n , that there exists \tilde\delta=\tilde\delta(p,n)>0 small such that if \Omega is a \delta -Reifenberg flat domain with \delta<\tilde\delta , then p -harmonic measure is concentrated on a set of \sigma -finite H^{n-1} -measure. We prove, for p \geq n , that for sufficiently flat Wolff snowflakes the Hausdorff dimension of p -harmonic measure is always less than n-1 . We also prove that if 2<p<n , then there exist Wolff snowflakes such that the Hausdorff dimension of p -harmonic measure is less than n-1 , while if 1<p<2 , then there exist Wolff snowflakes such that the Hausdorff dimension of p -harmonic measure is larger than n-1 . Furthermore, perturbing off the case p = 2, we derive estimates when p is near 2 for the Hausdorff dimension of p -harmonic measure.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
