Abstract

fetched live from OpenAlex

Abstract If is an integral model of a smooth curveXover a global fieldk, there is a localization sequence comparing theK-theory of andX. We show thatK1( ) injects intoK1(X) rationally, by showing that the previous boundary map in the localization sequence is rationally a surjection, forXof “GL2type” andkof positive characteristic not 2. Examples are given to show that the relativeG1term can have large rank. Examples of such curves include non-isotrivial elliptic curves, Drinfeld modular curves, and the moduli of -elliptic sheaves of rank 2.

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.
