Abstract

fetched live from OpenAlex

This paper is inspired by Aubin's 1979 result, which established that the best constant in the Sobolev inequality on the n-sphere, S^n, can be improved under the condition of vanishing first-order moments. Recent advancements by Hang and Wang (2021) showed that Aubin's improvement can be generalized to arbitrary higher-order moments. We further extend Hang and Wang's results to the Hardy-Sobolev inequality on S^n by deriving an associated concentration-compactness principle and imposing similar moment constraints. Finally, we briefly outline a framework for extending these results to higher-order Sobolev spaces.

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.
