Abstract

fetched live from OpenAlex

Let q = p s q=p^s be a prime power, F F a field containing a root of unity of order q q , and G F G_F its absolute Galois group. We determine a new canonical quotient G a l ( F ( 3 ) / F ) \mathrm {Gal}(F_{(3)}/F) of G F G_F which encodes the full mod- q q cohomology ring H ∗ ( G F , Z / q ) H^*(G_F,\mathbb {Z}/q) and is minimal with respect to this property. We prove some fundamental structure theorems related to these quotients. In particular, it is shown that when q = p q=p is an odd prime, F ( 3 ) F_{(3)} is the compositum of all Galois extensions E E of F F such that

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.
