Abstract

fetched live from OpenAlex

<div> The rank two Jacobi algebra J 2 is used to provide an interpretation of the twovariable Jacobi polynomials J (a,b,c) n,k (x, y) on the triangle, as overlaps between two representation bases. The subalgebra structure of J 2 depicted via a pentagonal graph is exploited to find the explicit expression of the two-variable functions in terms of univariate Jacobi polynomials. It is also seen to provide an explanation for the fact that the expansion on the basis J (a,b,c) n,k (x, y) of the polynomials obtained from the latter by permuting the variables x, y, z = 1 -xy and the parameters (a, b, c) is given in terms of Racah polynomials. The underlying order-three symmetry is discussed. </div>

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.
