Abstract

fetched live from OpenAlex

Let W be an irreducible Weyl group and W a its affine Weyl group. In [3] the author introduced an affine variety X Wa , called the Shi variety of W a , whose integral points are in bijection with W a . The set of irreducible components of X Wa provided results at the intersection of group theory, combinatorics and geometry. In this article we express the notion of orientation of alcoves in terms of the first cohomology group of W and the irreducible components of the Shi variety. We also provide modular equations in terms of Shi coefficients that describe explicitly the property of having the same orientation.

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.
