LeanPool.NavierStokesAndEuler.NavierStokes.ActualPrimaryCovariance

Covariance of the fixed physical primary family #

The selected primary phases, native matrices, masks, and physical labels are those of CorrectionInitialization.ActualPrimary. The finite family is assembled before averaging. The fixed starting threshold is retained.

Changing the common auxiliary cover does not change a diagonal average #

Zero masks really remove the selected native fields #

The same physical point in each fixed label's native coordinates #

Coverage by the fixed chosen labels #

Covariance of the literal initialized tangent pieces #

The exact finite low-band defect #

All-order bounds for the retained finite prefix #

Direct interfaces for the initial mean balance #

Actual closed support and separation on the common chart #

The support statements use the literal cut amplitude. Compactness of the padded native rectangle gives closed lifted support on the torus, so passing from nonzero values to topological support requires no false zero-germ claim at an edge. The common-chart disjointness statements retain the intersection with the genuine open domain.

Inactive physical labels vanish on entire slow fibers #

The radial coordinate is unrestricted here. A nonzero literal attached coefficient forces radial interior support and a nonzero actual mask, which imply membership in the fixed active-label set. On an inactive label the entire raw coefficient is therefore zero in an open slow neighborhood; this also removes its actual curl and Gaussian term.
