Gaussian coverage for the actual scaled particular solves #
The cutoff used by the inverse is the separate Gaussian slot cutoff times the padded native-clock cutoff. The dyadic, radial, and slow source masks remain in the source and amplitude. Whole-path support, rather than a pointwise zero of the source, supplies zero germs for the actual Volterra solution.
Gaussian cutoff errors from support-local primitive estimates #
The analytic phase patch may be smaller than the closed periodization
cell. Only primitive amplitude/source/cutoff jets on that patch enter
the Gaussian estimate. On the remainder of the cell, actual input zero
germs imply a zero germ of the two-term cutoff error. The global source
complement is retained once, exactly as in CopyData.globalGaussian.
Enlarging the set of estimated points through zero neighborhoods preserves the actual native derivative constants.
A zero cutoff alone leaves the source. Both zero germs are used.
Gaussian and plateau hypotheses are imposed only on the analytic
patch C. No raw-field derivative bound on K \ C is assumed.
The source on the complement of all cells is kept and estimated
through hcomplement; it is not replaced by a copywise sum of sources.
Gaussian absorption with an arbitrary extra index #
The index may be the pair (spatial label, lattice copy). Both the Gaussian envelope and the native length are allowed to depend on it.
Actual source jets on the uncovered set, with constants chosen before the spatial label as well as the band and point.

The constants precede every spatial label, band and native copy. The uncovered source is included with its own equally uniform jet bound.
The literal harmonic residual supplies the complement #
If an excluded harmonic tail remains outside the cells, its actual uniform class transfers to the literal incoming source. It is kept in the final global Gaussian, not set to zero.

Instances For
Every real power is gained by the literal global Gaussian error,
including its uncovered-source term. The source support assumptions are
on the incoming harmonic coefficients; all output zero germs and all
cutoff estimates are derived. The modal controls are precisely those
constructed by ScaledActualParticularControl.
The local source estimate consumed above follows from the actual current harmonic residual classes, with the angular variable inserted by the literal source-family definition.

Instances For
The full actual source mask retains all its factors. Its support is contained in the closed slow core and the Gaussian support rectangle; none of the dyadic or radial factors is asserted to equal one.
Clock transport of the full actual mask supplies the exact closed source region used above. The spatial mask remains part of the source.
A weighted companion for physical edge estimates #
Only the dyadic exponent is absorbed. The flat edge weight is retained for the subsequent physical extension estimate.
The Gaussian gain preserves sqrt(zeta) exactly. Unlike the
unweighted absorption theorem, this estimate retains its original
polynomial inverse-edge degree; the positive edge weight remains
available to absorb that degree in physical coordinates.
Weighted counterpart of the frozen LGB gluing theorem. The source complement retains the same edge weight and still occurs exactly once.
The actual Gaussian error retains precisely the flat sqrt(zeta)
weight at every decay exponent. This companion is suitable for the
physical local-source bounds; no completed edge extension is assumed.
