Abstract

fetched live from OpenAlex

Abstract In this article, we study the correspondence between the geometry of del Pezzo surfaces S r and the geometry of the r -dimensional Gosset polytopes ( r − 4) 21 . We construct Gosset polytopes ( r −4) 21 in Pic Sr ꕕ ℚ whose vertices are lines, and we identify divisor classes in Pic S r corresponding to ( a − 1)-simplexes ( a ≤ r ), ( r − 1)-simplexes and ( r − 1)-crosspolytopes of the polytope ( r − 4) 21 . Then we explain how these classes correspond to skew a -lines( a ≤ r ), exceptional systems, and rulings, respectively. As an application, we work on the monoidal transform for lines to study the local geometry of the polytope ( r −4) 21 . And we show that the Gieser transformation and the Bertini transformation induce a symmetry of polytopes 3 21 and 4 21 , respectively.

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.
