Abstract

fetched live from OpenAlex

We give explicit formulas for the L 4 L_{4} norm (or equivalently for the merit factors) of various sequences of polynomials related to the Fekete polynomials \[ f q ( z ) := ∑ k = 1 q − 1 ( k q ) z k f_{q}(z) := \sum ^{q-1}_{k=1} \left (\frac {k}{q}\right ) z^{k} \] where ( ⋅ q ) \left (\frac {\cdot }{q}\right ) is the Legendre symbol. For example for q q an odd prime, \[ ‖ f q ‖ 4 4 := 5 q 2 3 − 3 q + 4 3 − 12 ( h ( − q ) ) 2 \|f_{q}\|_{4}^{4} : = \frac {5q^{2}}{3}-3q+ \frac {4}{3} - 12 (h(-q))^{2} \] where h ( − q ) h(-q)

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.
