Abstract

One-Sentence Summary Speed-Driven Categorization (SDC) is a minimal extension of renormalization group theory that classifies effective actions by powers of c^n, reinterpreting RG flow as a hierarchical structure of causality, information, and geometry without introducing new physical entities. Speed-Driven Categorization (SDC):A Minimal cⁿ-Hierarchical Extension of Renormalization Group Flow ↑ c^n (SDC hierarchy) │ 10F ────●─────── Topology / Extreme QG │ 9F ────●─────── High curvature, ultra-density │ 8F ────●─────── Nonlinear EM (F·F)^2 │ 6F ────●─────── Spacetime dissipation / viscosity │ 5F ────●─────── Planck power │ 4F ────●─────── Maximum tension / Einstein gravity │ 3F ────●─────── EM–particle boundary │ 1F ────●─────── Composite mass (QCD) │ 0F ────●─────── 1/α(μ) ← RG connector │ B1 ────●─────── Photon / information │ B3 ────●─────── Planck length │ B4 ────●─────── κ = 8πG / c^4 │ B8 ────●─────── Vacuum impedance │ └────────────────────────→ log μ (standard RG flow) Figure 1 | Conceptual RG–SDC flow structure.The horizontal axis represents the conventional renormalization group flow in energy scale log⁡μ\log \mulogμ.The vertical axis labels the hierarchical organization by powers of cnc^ncn, corresponding to dominant causal, informational, and geometric regimes.Each node denotes a prevailing effective description rather than a fundamental theory.No new degrees of freedom are introduced; the diagram represents a reorganization of existing effective theories into a two-dimensional flow structure. Effective Action S_eff │ ▼ Decomposition by powers of c │ S_eff = Σ c^n L_n │ ┌────────┴───────┐ │ │ RG flow (μ) SDC flow (n) horizontal vertical │ │ ▼ ▼ Running couplings Causality / g_i(μ) Information / Geometry dominance │ │ └────────┬───────┘ ▼ Effective description (no new DOF) Figure 2 | Logical structure of Speed-Driven Categorization (SDC).The effective action is decomposed into contributions ordered by powers of cnc^ncn.Conventional renormalization group flow acts horizontally in energy scale μ\muμ, while SDC introduces a vertical classification according to causal, informational, and geometric dominance. The construction adds no new degrees of freedom and serves as a structural reorganization of effective field descriptions. SDC の数式的最小モデル (Minimal Mathematical Formulation) 1. 基本公理(Axioms) A1. c はスケール生成子 光速 ccc は単なる定数ではなく、因果構造・エネルギー流・情報伝播を同時に正規化する生成子である。 A2. 有効作用は cⁿ で階層分解できる 任意の有効作用 SeffS_{\mathrm{eff}}Seff は次のように展開可能: Seff=∑n∈Zc n Ln[ϕi,∂μ,gμν;μ]\boxed{ S_{\mathrm{eff}} = \sum_{n\in\mathbb{Z}} c^{\,n}\, \mathcal{L}_{n} \bigl[\phi_i,\partial_\mu,g_{\mu\nu};\mu\bigr] }Seff=n∈Z∑cnLn[ϕi,∂μ,gμν;μ] Ln\mathcal{L}_nLn:cⁿ 階層に属する有効ラグランジアン密度 粒子種は仮定しない(場・結合・幾何のみ) 2. cⁿ 階層と次元整合条件 定義(SDC階層条件) dim⁡ ⁣(cnLn)=[action density]\dim\!\left(c^{n}\mathcal{L}_n\right) = [\text{action density}]dim(cnLn)=[action density] よって Ln∼1cn×(energy)4\mathcal{L}_n \sim \frac{1}{c^{n}} \times (\text{energy})^4Ln∼cn1×(energy)4 これは 高 n:エネルギー流・張力・曲率 低 n:情報・位相・幾何的揺らぎ を自動的に分類する。 3. SDC–RG 方程式(中核) 通常の RG: μdgidμ=βi(g)\mu \frac{d g_i}{d\mu} = \beta_i(g)μdμdgi=βi(g) SDC 拡張: (μ∂∂μ+βc(c)∂∂c)Ln=∑mγnm Lm\boxed{ \left( \mu\frac{\partial}{\partial\mu} + \beta_c(c)\frac{\partial}{\partial c} \right) \mathcal{L}_n = \sum_m \gamma_{nm}\, \mathcal{L}_m }(μ∂μ∂+βc(c)∂c∂)Ln=m∑γnmLm 解釈 RG flow は 横方向(μ) SDC flow は 縦方向(n) γnm\gamma_{nm}γnm:cⁿ 階層間の混合(抑制付き) 4. 階層混合の抑制条件(安定性) SDC が暴走しないための条件: ∣γnm∣ ∝ (EEPl)∣n−m∣\boxed{ |\gamma_{nm}| \;\propto\; \left(\frac{E}{E_{\mathrm{Pl}}}\right)^{|n-m|} }∣γnm∣∝(EPlE)∣n−m∣ 👉 通常エネルギーでは 隣接階層のみ有効 高次(±8F, ±10F)は自然に不可視 これは 有効理論として極めて健全。 5. 仮想光子の定義(最小) Dμν(n)(k)=1cnPμν(k)k2\boxed{ D^{(n)}_{\mu\nu}(k) = \frac{1}{c^{n}} \frac{P_{\mu\nu}(k)}{k^2} }Dμν(n)(k)=cn1k2Pμν(k) 実在粒子ではない 同一ゲージ場の異なる c 正規化モード B1(n = −1)が通常の光子に一致 cⁿ 階層の RG Flow 図(概念可視化) ↑ c^n (SDC flow) │ 10F ────●──────── トポロジー / 極限QG │ 9F ────●──────── 高曲率・超密度 │ 8F ────●──────── 非線形EM (F·F)^2 │ 6F ────●──────── 時空散逸 / 粘性 │ 5F ────●──────── Planck Power │ 4F ────●──────── 最大張力 / Einstein │ 3F ────●──────── EM–粒子境界 │ 1F ────●──────── 複合質量(QCD) │ 0F ────●──────── 1/α(μ) ← RG fixed connector │ B1 ────●──────── 光子 / 情報 │ B3 ────●──────── Planck 長 │ B4 ────●──────── κ = 8πG/c^4 │ B8 ────●──────── 宇宙インピーダンス │ └────────────────────→ log μ (通常の RG flow) 6. 図の読み方 横方向:通常の RG(エネルギースケール) 縦方向:SDC(因果・情報・幾何の支配層) 各点は fixed theory ではなく支配的な有効記述 👉「新しい理論空間を増やさず、既存理論を再配置しただけ」という点が最大の防御 CC0 public-domain open-source researchers who resonate with the C⁹ boundary and its non-proprietary philosophy — and the shared ideal horizon it implies — are welcome to make informal contact
