Tri-Tetra Theory (TTT): Geometric Origin of the Three-Generation Structure...

The three-generation structure of elementary particles — the existence of exactly three families of quarks and leptons — is not explained by the Standard Model, which treats the generation number as an external parameter. We address this problem within the Tri-Tetra Theory (TTT), whose foundational axiom is the Bipolar Zero relation Y = 1/X. We demonstrate that the hyperbola XY = 1, under stereographic projection φ: ℝ² → S², maps to a closed curve with both asymptotes converging to the north pole (0, 0, 1) (numerically verified to 10⁻¹⁶). The three-variable odd-parity Bipolar Zero product XYZ = −1, subject to spherical constraint, has exactly four critical points forming a regular tetrahedron inscribed in S², with all six edge lengths equal to 2√2 and vector sum identically zero. The n-variable extension X₁X₂⋯Xₙ = ±1 generates 2^ (n−1) critical points (the Dₙ half-hypercube) with universal minimum edge length 2√2, verified for n = 1, …, 6. The generation number G (n) = 2^ (n−1) − 1 equals 3 uniquely at n = 3: three-dimensional physical space is the unique dimension yielding exactly three generations under the Bipolar Zero axiom with one vertex designated as the observer (jJ-axis). The TTT six-axis framework maps to the D₆ root system (60 roots), contained in E₈ (240 roots) via D₆ ⊂ E₇, E₆ ₂ E₇ ⊂ E₈ (all verified). Three structural gaps are identified as open problems: (1) D₆ → E₆: spinorial extension from integer (±1) to half-integer (±1/2) root components; (2) E₆ → E₇: time-axis extension (54 = 27×2 = 3³×2 roots) ; (3) E₇ → E₈: full unification (E₈ dim. 248 = 8× (2⁵−1) ). The Koide formula K = 2/3 (accurate to 0. 001%) is identified as a consistency constraint involving the (1, 1, 1) observer direction. The muon g−2 anomaly (~4. 2σ) is identified as a target for the iI-axis resonance mechanism.
