... solution. For adiabatic perturbations, we can find a gauge invariant quantity that is also constant for superhorizon modes, ζ ≡ Φ + 1 H (Φ  + HΦ) = u z  R c , for k  aH R c = gauge-invariant curvature ... equations to study deviations from spatial uniformity. The smallness of cosmic microwave background anisotropies gives some justification for this perturbative approach at least...
