Fluctuation bounds for the two-grid transport #
The fluctuation and Whitney estimates consumed by the two-grid transport
p.two.grid.transport. Stationarity pays only the number of scale-k parents for their
joint history maximum; the averaged lattice row and the two Whitney row shapes are bounded
as Schatten moments, with the operator-norm, weighted-moment and finite-row inequalities
that let a single nonnegative envelope dominate every old-history generation. The old bulk
family, the boundary rows above k and the root of the weighted moment are then paid by the
profile, after canceling the exact parent-cardinality and dimension factors, so the whole
old-history contribution keeps the printed terminal decay.
Stationarity pays only the number of scale-k parents for their joint history maximum. Every parent keeps the same translation across all child generations.
Averaging at the even moment bigQ, with the actual terminal mean as R, then transport from the self normalization. Both the row-average bound and log-det loss are consumed; the row may be empty.
The Whitney two-grid bound supplies both square-sum coefficients and the actual infinite mass identity. All constants are chosen before the grids and target.
Operator-norm transport is pointwise, so it can be used before any random maximum.
A positive finite row mass multiplies the maximum of its entry norms. Only the fixed dimension converts its final operator norm to Schatten norm.
A single random envelope controls all old-history generations in the new target. Its moment pays only the finite family of scale-k parents.
The old-history norm comparison after taking the Q-th power, including the exact d-dimensional parent-count exponent.
Above k, target counting and averaging leave precisely the old profile weight. Nonnegative gamma and the positive bulk decay exponent pay the rest.
Boundary averaging preserves a summable coefficient in the separation of the target and source generations, after the exact target-count loss.
The mixed norm at the fixed natural moment has the printed Bochner moment. Membership records that this is an integrable random moment.
The averaging estimate gives the actual row moment, for both Whitney row shapes.
The old-history half of the bulk family retains one common envelope under the joint maximum. Its exact coefficient is recorded before absorption.
The powered old-history factor is paid by the first profile component. The constant records the fixed enlargement of the parent family.
The old bulk family is paid by the first summand of the actual profile.
The boundary rows above k are paid by the final profile sum. Weighted convexity is applied before exchanging the target and source generations.
