Abstract

fetched live from OpenAlex

Let N be a compact domain with weakly two-convex boundary ∂N in a Riemannian 4-manifold M with nonnegative isotropic curvature. If D is a stable minimal disk in N with ∂D ⊂ ∂N that solves the free boundary problem, then D is infinitesimally holomorphic; moreover, it is ± holomorphic if M is a Kähler surface with positive scalar curvature, and it is holomorphic for some complex structure if M is a hyperkähler surface. We also show that if N is a compact domain in M of dim M ≧ 4 with nonnegative isotropic curvature and ∂N is two-convex, then π 1 ( ∂N ) → π 1 ( N ) is injective.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
