Abstract

fetched live from OpenAlex

We apply the theory of Seshadri stratifications to embedded toric varieties Xp ⊆ P (V ) associated with a normal lattice polytope P. The approach presented here is purely combina- torial and completely independent of [1]. In particular, we get a close connection between a certain class of triangulations of the polytope P, Seshadri stratifications of Xp arising from torus orbit closures, and the associated degenerate semi-toric varieties. In the last section we show that the approach here and the one in [1] produce the same quasi-valuations and hence the same degenerations of Xp.

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.
