Retain actual R/S/reflection/positive partitions, the same original D graph/density/closability/closed closure, ONE u and all-domain variational identity, original local u/G/r square integrability, every original C1 weak-gradient test/C2 weak PDE, and every cutoff volumeL2/support/weak identity. For each cutoff produce actual weighted classes vW,AW,GW linked to v=chi*u, Gchi and Achi=inner(gradientW,Gchi)-Fchi, original (vW,GW) in D_y.closure.graph and ((alpha+eta^-1)/4)*norm(GW)^2≤norm(AW)^2.

\[\exists R,S\ \forall y\ \exists D_y\ \forall\varepsilon>0,f\ \exists u\ \forall\chi\in C_c^2:\quad(v_W,G_W)\in\operatorname{graph}\overline D_y,\quad\frac{\alpha+\eta^{-1}}4\|G_W\|_{L^2(S_y)}^2\le\|A_W\|_{L^2(S_y)}^2.\]

Exact module and namespace context

Proof roadmap

  1. 1Keep genuine source kernels, reflected potential and original resolvent

    Consume ConditionalLocalizedResolvent with exact source curvature/eta inputs. Retain its same J/R/S and true reflected density, positive partitions, original D before epsilon/f and ONE u before ALL C2 compact cutoffs. All original local/weak/volumeL2 identities remain visible.

  2. 2Reuse the exact quarter-scale Hessian lower bound

    The accepted ConditionalScoreDomain producer proves the lower Hessian bound for this explicit W_y. Extract only that pointwise fact; do not identify its auxiliary kernels with the resolvent kernels. Reflected and RGO operators/laws remain distinct.

  3. 3Apply the shared producer to the same localized weak data

    For each C2 cutoff extract actual volumeL2/support and every weak equation for v/Gchi/Fchi from the SAME u. Pass the true equality S_y=tilted(-W_y), original closable D/exact graph and actual lower curvature to the shared producer. It derives the actual weighted classes and same-D graph membership; the desired weighted conclusion is never a premise.

  4. 4Exercise a true nonquadratic source potential and C2 cutoff

    The focused Test uses V=3x^2/8+sin(x)/8 with curvature[1/2,1], eta in(0,1], actual R/S/D/u and cutoff rho(x)*(x^2)^(5/2), certified C2 and not required to be smooth of all orders. It extracts true weighted MemLp/AE, original graph membership and the exact quarter-constant inequality.

  5. 5Keep the scalar endpoint separate from larger paper obligations

    No jointly measurable fiber choice, cutoff removal, rough Hessian/global Bochner, adjoint/core identity, epsilon-zero/kernel/range/Poincare/BL or either main/composition follows from this packet. TV proximity still cannot transfer an unbounded expected cost.

Full assumptions and notation

All objects and hypotheses

  • Same finite-dimensional real Hilbert/Borel structure including dimension zero. Source V is C2; alpha,beta are NNReal with 0<alpha≤beta, actual all-point/all-vector alpha I≤Hess V≤beta I, eta>0 and beta*eta≤1.
  • Actual augmentation J=(x,x+sqrt(eta)*xi)#(mu*standardGaussian), common probability/disintegrating R/S, S_y=(2x-y)#R_y=volume.tilted(-W_y), W_y(z)=V((y+z)/2)+norm(z-y)^2/(8eta), C2 W_y and positive integrable partition are genuine parent conclusions. The accepted curvature parent yields HessW_y ≥ ((alpha+eta^-1)/4)I for this same explicit W, without equating its auxiliary kernels with the resolvent kernels.
  • Original dense closable exact compact-smooth gradient D_y and closed closure are fixed before epsilon/f. For every epsilon>0 and f in actual L2(S_y), ONE actual u precedes ALL real C2 compact cutoffs chi. Parent all-domain variational identity, original ordinary weak/local facts and actual localized v=chi*u, Gchi=chi*D.closure(u)+u*gradientchi, Fchi=chi*r+2inner(gradientchi,D.closure(u))+u*Deltachi, r=epsilon*u+inner(gradientW,D.closure(u))-f, are retained.

Mathematical proof

1. Keep genuine source kernels, reflected potential and original resolvent

Consume ConditionalLocalizedResolvent with exact source curvature/eta inputs. Retain its same J/R/S and true reflected density, positive partitions, original D before epsilon/f and ONE u before ALL C2 compact cutoffs. All original local/weak/volumeL2 identities remain visible.

\[W_y(z)=V((y+z)/2)+\|z-y\|^2/(8\eta),\quad S_y=Z_y^{-1}e^{-W_y}dz.\]
Corresponding Lean step

2. Reuse the exact quarter-scale Hessian lower bound

The accepted ConditionalScoreDomain producer proves the lower Hessian bound for this explicit W_y. Extract only that pointwise fact; do not identify its auxiliary kernels with the resolvent kernels. Reflected and RGO operators/laws remain distinct.

\[\nabla^2 W_y\succeq\frac{\alpha+\eta^{-1}}4 I.\]
Corresponding Lean step

3. Apply the shared producer to the same localized weak data

For each C2 cutoff extract actual volumeL2/support and every weak equation for v/Gchi/Fchi from the SAME u. Pass the true equality S_y=tilted(-W_y), original closable D/exact graph and actual lower curvature to the shared producer. It derives the actual weighted classes and same-D graph membership; the desired weighted conclusion is never a premise.

\[v=\chi u,\quad G_\chi=\chi G+u\nabla\chi,\quad A_\chi=\langle\nabla W_y,G_\chi\rangle-F_\chi.\]

4. Exercise a true nonquadratic source potential and C2 cutoff

The focused Test uses V=3x^2/8+sin(x)/8 with curvature[1/2,1], eta in(0,1], actual R/S/D/u and cutoff rho(x)*(x^2)^(5/2), certified C2 and not required to be smooth of all orders. It extracts true weighted MemLp/AE, original graph membership and the exact quarter-constant inequality.

\[\frac{1/2+\eta^{-1}}4\|G_W\|_{L^2(S_y)}^2\le\|A_W\|_{L^2(S_y)}^2.\]
Corresponding Lean step

5. Keep the scalar endpoint separate from larger paper obligations

No jointly measurable fiber choice, cutoff removal, rough Hessian/global Bochner, adjoint/core identity, epsilon-zero/kernel/range/Poincare/BL or either main/composition follows from this packet. TV proximity still cannot transfer an unbounded expected cost.

\[\text{compact scalar coercivity only; global/Poincare/BL/main/composition open}.\]

Source fixes originalD before epsilon/f and ONEu before ALLC2chi. No supplied weighted domain/core/convergence/coercivity certificate; no rough classical Hessian or full adjoint/generator-core identity, globalcutoff/tail/Bochner,epsilon0/kernel/range/noncompactlinear/Poincare/BL/jointmeasurablechoice/main/composition. Reflected quarter/fourfold constants exact. TV never transfers unbounded cost.

Samplinglib prose is not a quotation or a source-equivalence certificate. Definitions and aliases are explained as constructions, not counted as new mathematical proofs.
