Abstract

fetched live from OpenAlex

Let X be a projective algebraic manifold and let CHr (X) be the Chow group of algebraic cycles of codimension r on X, modulo rational equivalence. Working with a candidate Bloch- Beilinson filtration {Fν}ν≥0 on CHr (X) ⊗ ℚ due to the second author, we construct a space of arithmetic Hodge theoretic invariants ∇Jr,ν(X) and corresponding map ϕr,ν X : GrνF CHr (X)⊗ℚ → ∇Jr,ν(X), and determine conditions on X for which the kernel and image of ϕr,νX are "uncountably large".

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
