Abstract

fetched live from OpenAlex

Abstract For given multiplicative functionf, with |f(n)| ≤ 1 for alln, we are interested in how fast its mean value (1/x) Σn≤xf(n) converges. Halász showed that this depends on the minimumM(overy∈ ℝ) of Σp≤x(1 – Re(f(p)p–iy)/p, and subsequent authors gave the upper bound ⪡ (1 +M)e–M. For many applications it is necessary to have explicit constants in this and various related bounds, and we provide these via our own variant of the Halász-Montgomery lemma (in fact the constant we give is best possible up to a factor of 10). We also develop a new type of hybrid bound in terms of the location of the absolute value ofythat minimizes the sum above. As one application we give bounds for the least representatives of the cosets of thek-th powers modp.

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.
