Abstract

fetched live from OpenAlex

Le présent mémoire contient deux articles reliés par le formalisme de l'ansatz de Bethe. Dans le premier article, l'opérateur de Heun de type Lie est identifié comme une spécialisation de la matrice de transfert d'un modèle de \(BC\)-Gaudin à un site dans un champ magnétique. Ceci permet de le diagonaliser à l'aide de l'ansatz de Bethe algébrique modifié. La complétude du spectre est démontrée en reliant les racines de Bethe aux zéros des solutions polynomiales d'une équation différentielle de Heun inhomogène. Le deuxième article aborde le sujet des représentations irréductibles de l'algèbre de Lie \(su(3)\) dans la réduction \(su(3) \supset so(3) \supset so(2)\). Cette manière de construire les représentations irréductibles de \(su(3)\) porte une ambiguïté qui empêche de distinguer totalement les vecteurs de base, ce qui mène à un problème d'étiquette manquante. Dans cet esprit, l'algèbre des deux opérateurs fournissant cette étiquette est examinée. L'opérateur de degré 4 dans les générateurs de \(su(3)\) est diagonalisé en se servant des techniques de l'ansatz de Bethe analytique.

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.
