The clause-(i) assembly of the annular decomposition #
ABK26, Section 4.1, the proof of p.mathcalE.annular.decomp, assembled end to
end at the literal flux-corrected carrier Support.fluxCorrectedError.
The chain composed here is the manuscript's own:
the (infinity,2) opening e.mathcal.E.eight.ess.bound (EightEss)
-> the two J-sums (field leg + transposed leg) (BlockResponse/DescendantLattice)
-> the annular cover (Step1, IsAnnularDecompPre)
-> the per-cube ugly estimate (UglyChain, IsUglyJEstimate)
-> e.mathcalE.annular.decomp.pre.zero (Resum.preZero_of_pre_and_ugly)
-> the three Step-3 resummations (Step3Producers)
-> e.mathcalE.annular.decomp (Step3.annularDecomp_of_preZero)
The two structural moves made explicit here #
- The transposed leg. The manuscript discharges the second
J-sum by asserting that "the right side ofe.mathcalE.annular.decomp.pre.zerodoes not change if we replace the field with its transpose". Here the two legs are run through the same composite with the same five right-hand families,sig,L2f,gradNf,gradTailSq; each of the five terms is therefore literally the same expression for the two legs, and the assertion is reduced to its one genuine content, the transposed leg's per-cube ugly estimate. pre.zero's fourth term carriesgrad(k_L - k_{n-2})while the Step-3 resummation display carriesgrad(k_m - k_{n-2}); the manuscript substitutes silently.
Part A -- the two arithmetic bridges of the opening #
The c_{2s} discount is linear in s. 1 - 3^(-2s) <= 4 s for
s >= 0, from 1 + y <= exp y and log 3 <= 2. This is what converts the
normalizing factor c_{2s} of the (infinity,2) opening into the prefactor
C s of the first conclusion term.
The scale-index bridge. The (infinity,2) opening sums over the depth
l in N; every downstream module sums over the scale n <= m. Under
n = m - l the two weighted sums agree.
Part B -- the m-vs-L tail routing #
e.mathcalE.annular.decomp.pre.zero's fourth term carries the gradient of `k_L
- k_{n-2}
while the Step-3 resummation display carries the gradient ofk_m - k_{n-2}; the manuscript substitutes one for the other without comment. Honestlyk_L - k_{n-2} = (k_m - k_{n-2}) + (k_L - k_m), and the triangle inequality leaves ak > m` tail.
This lemma states the routing: if the per-cube estimate holds with the tail
included in the fourth slot, at a tail budget Ktail * gradM proportional to
the fifth term's own content, then it holds in the clean five-term shape at the
constant (1 + Ktail) C. The move is available because on the annular region
n <= j - 1 <= m - 1 the fifth term's weight w_gamma = 3^((s+gamma)(m-n))
dominates the fourth's w = 3^(s(m-n)), so the tail is absorbed by the term
whose content is exactly the k >= m object.
Part C -- one leg of the opening, taken to the pre.zero shape #
One leg of the opening, taken to the pre.zero shape.
Given
hess-- the leg's contribution to the(infinity,2)opening, in the shapeeightEss_of_blockResponse_leproduces it;hpreA-- the Step-1 annular cover at the leg's grid family;hugly-- the per-cube ugly estimate at the manuscript's weights;- the four summability facts of
preZero_of_pre_and_ugly,
the leg satisfies the five-term e.mathcalE.annular.decomp.pre.zero shape. The
work done here beyond preZero_of_pre_and_ugly is the conversion of the
c_{2s} prefactor into 4 Cbf s and the scale-index bridge.
Part D -- the four-term shape with separated constants #
The Step-3 four-term shape carries ONE constant across all four right-hand terms.

Instances For
The Step-3 regrouping at separated constants. The regrouping in which
the sigma-bar slot's extra s^(-1) is carried by the second term's exponent
rather than by the shared constant, so the output constant is s-free.
Part D' -- the two legs and the Step-3 regrouping #
The two-leg Step-3 regrouping.
The field leg and the transposed leg are both taken to the five-term pre.zero
shape at the same five right-hand families; adding them doubles the constant
and nothing else. This is the machine-visible content of the manuscript's
transpose remark: each of the five right-hand terms is literally the same
expression for the two legs, so "the right side does not change" is not a claim
about the terms at all -- its whole content is that the transposed leg admits
the same per-cube ugly estimate, which is the caller's hlegt.
The three Step-3 resummations are then discharged from their comparison inputs
(hshom, hcsL2, hcsGn) and the regrouping is clauseOneBound_of_preZero.
Part E -- the composite at the flux-corrected carrier #
gradTailSq M m omega = ( sum_{k >= m} 3^((2-gamma) m) ‖grad j_k‖_{W^{1,infinity}(Box_m)} )^2 .
The square is outside the sum; the printed display puts it inside, and the
inside-square variant cannot dominate the fifth pre.zero term.
