Abstract

fetched live from OpenAlex

Given a fixed binary form f(u,v) of degree d over a field k, the associated Clifford algebra is the k-algebra Cf=k{u,v}/I, where I is the two-sided ideal generated by elements of the form (αu+βv)d−f(α,β) with α and β arbitrary elements in k. All representations of Cf have dimensions that are multiples of d, and occur in families. In this article, we construct fine moduli spaces U=Uf,r for the irreducible rd-dimensional representations of Cf for each r≥2. Our construction starts with the projective curve defined by the equation wd=f(u,v), and produces Uf,r as a quasiprojective variety in the moduli space of stable vector bundles over C with rank r and degree dr=r(d+g−1), where g denotes the genus of C.

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.
