Derivation

In orthodox turbulence theory, intermittency is a ``correction’’ to K41—something that spoils the self-similar picture. In $τ$, intermittency is primary: it arises because the fiber $T^2$ can collapse to a point, concentrating energy on co-dimension-2 filaments. Intermittency is not a perturbation; it is a structural feature of the fibered product.

The collective dynamics predictions of Category $τ$ derive from a single structural fact: $(T^2) = 2$.

  • She–L'ev\^eque from fibration: $β$ and $C_0$ are structural constants of $τ^3 = τ^1 ×_f T^2$, derived from the fiber dimension (Theorem (thm:ch65-she-leveque)). Agreement $<1%$ for all $p ≤ 12$.
