From 03b6e0c10b20a773d51b5852cc144bbd658c0f3a Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 24 Jan 2026 15:41:42 +0000 Subject: [PATCH 1/3] feat(moonshine): add Monster dimension via Coxeter numbers formula MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the fundamental Monster-Coxeter relation: dim(M₁) = (b₃ - h(G₂)) × (b₃ - h(E₇)) × (b₃ - h(E₈)) = 71 × 59 × 47 = 196883 This expresses the Monster group's smallest faithful representation dimension purely in terms of the third Betti number b₃=77 and Coxeter numbers of exceptional Lie algebras. Changes: - Core.lean: Add Coxeter numbers h_G2=6, h_E6=12, h_E7=18, h_E8=30 - MonsterCoxeter.lean: New module with main theorem and structural relations - JInvariant.lean: Add j-coefficient ratio observations (c₂/c₁ ≈ 109) - Moonshine.lean: Import and integrate MonsterCoxeter module The formula is exact (no remainder), intrinsic (fundamental invariants), and connects Monstrous Moonshine to exceptional Lie theory via G₂-geometry. --- Lean/GIFT/Core.lean | 27 ++++ Lean/GIFT/Moonshine.lean | 17 ++- Lean/GIFT/Moonshine/JInvariant.lean | 39 +++++- Lean/GIFT/Moonshine/MonsterCoxeter.lean | 161 ++++++++++++++++++++++++ 4 files changed, 235 insertions(+), 9 deletions(-) create mode 100644 Lean/GIFT/Moonshine/MonsterCoxeter.lean diff --git a/Lean/GIFT/Core.lean b/Lean/GIFT/Core.lean index 24acbf0..745e929 100644 --- a/Lean/GIFT/Core.lean +++ b/Lean/GIFT/Core.lean @@ -96,6 +96,33 @@ def dim_F4 : ℕ := 52 -- Note: dim_G2 and rank_G2 come from Algebraic.G2 +-- ============================================================================= +-- COXETER NUMBERS +-- ============================================================================= + +/-- Coxeter number of G₂. + The Coxeter number h is the order of a Coxeter element in the Weyl group. + For G₂: h = 6, and |G₂ roots| = h × rank = 6 × 2 = 12. -/ +def h_G2 : ℕ := 6 + +/-- Coxeter number of E₆. + h(E₆) = 12, and |E₆ roots| = 12 × 6 = 72. -/ +def h_E6 : ℕ := 12 + +/-- Coxeter number of E₇. + h(E₇) = 18, and |E₇ roots| = 18 × 7 = 126. -/ +def h_E7 : ℕ := 18 + +/-- Coxeter number of E₈. + h(E₈) = 30, and |E₈ roots| = 30 × 8 = 240. -/ +def h_E8 : ℕ := 30 + +-- Certifications for use in norm_num +theorem h_G2_certified : h_G2 = 6 := rfl +theorem h_E6_certified : h_E6 = 12 := rfl +theorem h_E7_certified : h_E7 = 18 := rfl +theorem h_E8_certified : h_E8 = 30 := rfl + -- ============================================================================= -- GEOMETRY: K7 MANIFOLD -- ============================================================================= diff --git a/Lean/GIFT/Moonshine.lean b/Lean/GIFT/Moonshine.lean index 4dc2300..e9e9f9e 100644 --- a/Lean/GIFT/Moonshine.lean +++ b/Lean/GIFT/Moonshine.lean @@ -1,22 +1,24 @@ -- GIFT Monstrous Moonshine Module --- v3.3.10: Monster group, j-invariant, supersingular primes, and Monster-Zeta Moonshine +-- v3.3.11: Monster-Coxeter formula added -- -- This module provides: -- -
