Abstract

fetched live from OpenAlex

Abstract These inequalities have obvious interpretations for the coefficients of trigonometric polynomials. Real trigonometric polynomials and those which are non-negative deserve to be treated separately. However, in view of Proposition 12.4.5, any estimate for the coefficients of real trigonometric polynomials has a counterpart for the coefficients of self-inversive polynomials. In addition, certain estimates for the coefficients of non-negative trigonometric polynomials, when combined with Lemma 12.2.4, lead us to interesting inequalities for the coefficients of polynomials. Due to its special significance, we shall also determine the sharp upper bound for the modulus of the sum of the coefficients of a sine polynomial.

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.
