Dimensional Decoupling

Dimensional Decoupling is the complete separation of a child domain from its parent after a Nova Without event: the two share no region and no causal influence passes between them. In a supercritical rupture the parent's dimensional boundaries are breached entirely and independent recursive fields with new causal structures are spawned. The book states the decoupling in its Nova Without topology rules as Σ‵ ∩ Σ′_child = ∅ together with causal independence, C_parent ⊥ C′_child, and it corresponds to the spatial-separation and disconnect conditions of the Universe Isolation Constraints (Ω₁ ∩ Ω₀ = ∅; ∂Ω₁/∂Ω₀ = 0). The book compares it to string-theory brane-collision models in which ruptured higher-dimensional boundaries seed new causal regions, and contrasts it with the Nova Within regime, where topology is preserved and large-scale coherence persists. It connects to Nova Without Topology Transformation, Universe Isolation Constraints, Child Universe Spatial Separation, Child Universe Disconnect Condition, Nova Without and Causal Disconnection.
