Abstract

fetched live from OpenAlex

The beautiful Beraha–Kahane–Weiss (BKW) theorem has found many applications within graph theory, allowing for the determination of the limits of zeros of graph polynomials in a wide range of settings such as chromatic polynomials, network reliability, and generating polynomials related to independence and domination. However, the proof only provides solutions for linear recurrence relations of polynomials whose characteristic polynomials have simple zeros. Here we extend the class of functions to which the BKW theorem can be applied, and provide some applications in combinatorics.

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.
