Key Points

  • The aim is to reveal a unifying structure for algebraic invariants associated with the Conceptual and Extended Triptychs.
  • Defined the family of quadratic polynomials ℋ_c.
  • Established the empirical law c = 3 − N(u_fundamental) for four simple fields.
  • Proved a universal Galois theorem for the composita of quadratic fields.
  • Verified norms for products of canonical roots of ℋ_{c_i} on multiple composita.
  • Proposed a physical interpretation for the algebraic results based on sector decomposition.
  • Nine algebraic invariants of TC/TE have norm −1/c independently of the parameter a.
  • The established law holds for fields ℚ(√2), ℚ(√3), ℚ(√5), and ℚ(√6).
  • The Galois theorem shows that the global norm for products of canonical roots follows the derived formula, validated for five composita.

Abstract

EN DESCRIPTION This note extends the Algebraic Note TC V1 (DOI 10. 5281/zenodo. 19581493) by identifying a unifying structure underlying the algebraic invariants of the Conceptual Triptych (TC) and the Extended Triptych (TE). We define the family of quadratic polynomials ℋc = c·x² − a·x − 1 = 0, a ∈ ℤ and show that nine fundamental invariants of TC/TE (Table 3. 1) all have algebraic norm −1/c independently of a. We establish the empirical law c = 3 − N (ufundamental), where N is the norm of the fundamental Pell unit of the associated real quadratic field: the law holds for all four simple fields of TC/TE (ℚ (√2), ℚ (√3), ℚ (√5), ℚ (√6) ), with confirmed extrapolation for ℚ (√3). We prove a universal Galois theorem for the composita ℚ (√D₁, …, √Dₙ): for any product x = x₁·…·xₙ of canonical roots of the ℋ₂㶁, the global norm equals N (x) = (−1) ^ (n·2^ (n−1) ) / (c₁·c₂·…·cₙ) ^ (2^ (n−1) ), verified on five composita (three for n = 2, two for n = 3). We finally propose a physical interpretation of the algebraic results through the sector decomposition hypothesis of the TC: physical fields living in composita emerge as products of independent sub-fields, one for each relevant quadratic field. Version 2 — 17 April 2026. Supplement to TC V22 (DOI 10. 5281/zenodo. 19579065) and TE V3 (DOI 10. 5281/zenodo. 19626511). DESCRIPTION FR Cette note prolonge la Note algébrique TC V1 (DOI 10. 5281/zenodo. 19581493) en identifiant une structure unificatrice sous-jacente aux invariants algébriques du Triptyque Conceptuel (TC) et du Triptyque Étendu (TE). On définit la famille de polynômes quadratiques ℋc = c·x² − a·x − 1 = 0, a ∈ ℤ et l’on montre que neuf invariants fondamentaux de TC/TE (Tableau 3. 1) ont pour norme algébrique −1/c indépendamment de a. On établit la loi empirique c = 3 − N (ufondamentale), où N est la norme de l’unité fondamentale de Pell du corps quadratique réel associé: loi vérifiée sur les quatre corps simples du TC/TE (ℚ (√2), ℚ (√3), ℚ (√5), ℚ (√6) ), avec confirmation de l’extrapolation pour ℚ (√3). On démontre un théorème galoisien universel pour les composita ℚ (√D₁, …, √Dₙ): pour tout produit x = x₁·…·xₙ de racines canoniques des ℋ₂㶁, la norme globale vaut N (x) = (−1) ^ (n·2^ (n−1) ) / (c₁·c₂·…·cₙ) ^ (2^ (n−1) ), vérifié sur cinq composita (trois pour n = 2, deux pour n = 3). On propose enfin une lecture physique des résultats algébriques à travers l’hypothèse de sectorisation du TC: les champs physiques qui vivent dans les composita émergent comme produits de sous-champs indépendants, un par corps quadratique pertinent. Version 2 — 17 avril 2026. Supplément à TC V22 (DOI 10. 5281/zenodo. 19579065) et TE V3 (DOI 10. 5281/zenodo. 19626511).
