Proof roadmap

1Construct the original actual resolvent before choosing cutoffs
Consume LocalizedWeakResolvent on the SAME original closable exact compact-gradient graph. Its ONE u retains every local-volume/ordinary weak equation and every C2 cutoff equation. Set G=D.closureu and a=f-epsilon*u in genuine weighted L2. Do not assume the unlocalized inner(gradientW,G) or ordinary PDE residual is globally weighted L2.
2Derive linear drift and true scale-uniform cutoff bounds
The accepted Hessian secant integral and both source bounds imply norm(gradientW(x))≤b+M*normx, b=normgradientW0. Choose actual radial chi_n with radius n+1. Its true Riesz gradient bound C1/R, outer derivative zero and Laplacian trace bound C2/R^2 have constants before all radii. The second-derivative API is used only in the nontrivial branch; E0 is handled separately.
3Produce weighted L2 convergence through actual integrable squares
Bounded measurable coefficients times real/vector L2 functions are genuinely MemLp. Apply dominated integral convergence to squared norms and the true L2 norm-square integral; take square roots to get quotient convergence. Actual chi_n converges pointwise to1 and is in[0,1], hence chi_n*G and chi_n*a converge in weighted L2. Quotient subtraction is identified by explicit AE links.
4Control the drift commutator without an extra position moment
Outside normx≥2R the cutoff gradient vanishes. Inside, true linear drift gives a scale-uniform bound C1*(b+2M) for its drift product when R≥1. The generator coefficient c_n=inner(gradientW,gradientchi_n)-Deltachi_n is uniformly bounded and tends pointwise to0 by the actual derivative estimates. Dominated L2 then controls c_n*u using only weighted uL2, not norm(x)*u.
5Derive simultaneous actual localized gradient/generator limits
Use the genuine localized expressions Gchi=chiG+u*gradientchi and Fchi=chi*r+2inner(gradientchi,G)+u*Deltachi. Cancellation gives Achi=inner(gradientW,Gchi)-Fchi=chi*a-2inner(gradientchi,G)+c_n*u. The three errors are actual weighted MemLp/classes converging to0; thus Gchi→G and Achi→a. Preserve the sign and coefficient2; no separate global drift/PDE L2 premise is introduced.
6Apply actual compact coercivity and pass both squared norms
For each true smooth compact cutoff, pass its actual ordinary weak data to CompactWeightedPoissonCoercivity, which produces actual weighted AE classes, SAME original closure graph and scalar inequality. Identify these with the quotient classes of the true localized functions by AE extensionality. Pass norm and square limits to get the global scalar inequality. In E0, all vector L2 classes are zero, so the same inequality follows without the nontrivial derivative API.
7Test the SAME variational equation at u
The actual energy identity is epsilon*normu^2+normG^2=inner(f,u). Expand the residual squared norm using the real Hilbert identity; it equals normf^2-epsilon^2*normu^2-2epsilon*normG^2 and is at most normf^2. This positive-epsilon statement supplies no epsilon-zero limit, kernel theorem, Poincare, BL or main completion.

Full assumptions and notation

All objects and hypotheses

Finite real Hilbert/Borel E, including dimension0; canonical full-space volume. W is C2, exp(-W) genuinely integrable and Z positive. The actual input mu equals volume.tilted(-W). Real constants satisfy 0<m≤M and all-point/all-vector m*norma^2≤HessW(x)[a,a]≤M*norma^2. Both bounds are used to derive true linear drift.
Original weighted L2 partial real-linear gradient D is closable with its exact graph: actual AE classes of compact C-infinity functions and their genuine gradients. D precedes every epsilon>0 and f in L2(mu). No final closed-domain, generator-core, limit or coercivity certificate is given. The actual resolvent is constructed from this original graph.

Mathematical proof

1. Construct the original actual resolvent before choosing cutoffs

Consume LocalizedWeakResolvent on the SAME original closable exact compact-gradient graph. Its ONE u retains every local-volume/ordinary weak equation and every C2 cutoff equation. Set G=D.closureu and a=f-epsilon*u in genuine weighted L2. Do not assume the unlocalized inner(gradientW,G) or ordinary PDE residual is globally weighted L2.

\[a=f-\varepsilon u,\quad G=\overline Du,\quad r=\langle\nabla W,G\rangle-a.\]

2. Derive linear drift and true scale-uniform cutoff bounds

The accepted Hessian secant integral and both source bounds imply norm(gradientW(x))≤b+M*normx, b=normgradientW0. Choose actual radial chi_n with radius n+1. Its true Riesz gradient bound C1/R, outer derivative zero and Laplacian trace bound C2/R^2 have constants before all radii. The second-derivative API is used only in the nontrivial branch; E0 is handled separately.

3. Produce weighted L2 convergence through actual integrable squares

Bounded measurable coefficients times real/vector L2 functions are genuinely MemLp. Apply dominated integral convergence to squared norms and the true L2 norm-square integral; take square roots to get quotient convergence. Actual chi_n converges pointwise to1 and is in[0,1], hence chi_n*G and chi_n*a converge in weighted L2. Quotient subtraction is identified by explicit AE links.

4. Control the drift commutator without an extra position moment

Outside normx≥2R the cutoff gradient vanishes. Inside, true linear drift gives a scale-uniform bound C1*(b+2M) for its drift product when R≥1. The generator coefficient c_n=inner(gradientW,gradientchi_n)-Deltachi_n is uniformly bounded and tends pointwise to0 by the actual derivative estimates. Dominated L2 then controls c_n*u using only weighted uL2, not norm(x)*u.

\[|c_n(x)|\le C_1(b+2M)+C_2,\quad c_n(x)\to0,\quad c_nu\to0\text{ in }L^2(\mu).\]

5. Derive simultaneous actual localized gradient/generator limits

Use the genuine localized expressions Gchi=chiG+u*gradientchi and Fchi=chi*r+2inner(gradientchi,G)+u*Deltachi. Cancellation gives Achi=inner(gradientW,Gchi)-Fchi=chi*a-2inner(gradientchi,G)+c_n*u. The three errors are actual weighted MemLp/classes converging to0; thus Gchi→G and Achi→a. Preserve the sign and coefficient2; no separate global drift/PDE L2 premise is introduced.

\[A_{\chi_n}=\chi_na-2\langle\nabla\chi_n,G\rangle+c_nu\to a,\quad G_{\chi_n}\to G.\]

6. Apply actual compact coercivity and pass both squared norms

For each true smooth compact cutoff, pass its actual ordinary weak data to CompactWeightedPoissonCoercivity, which produces actual weighted AE classes, SAME original closure graph and scalar inequality. Identify these with the quotient classes of the true localized functions by AE extensionality. Pass norm and square limits to get the global scalar inequality. In E0, all vector L2 classes are zero, so the same inequality follows without the nontrivial derivative API.

\[m\|G_{\chi_n}\|_\mu^2\le\|A_{\chi_n}\|_\mu^2\ \Longrightarrow\ m\|G\|_\mu^2\le\|a\|_\mu^2.\]

7. Test the SAME variational equation at u

The actual energy identity is epsilon*normu^2+normG^2=inner(f,u). Expand the residual squared norm using the real Hilbert identity; it equals normf^2-epsilon^2*normu^2-2epsilon*normG^2 and is at most normf^2. This positive-epsilon statement supplies no epsilon-zero limit, kernel theorem, Poincare, BL or main completion.

\[\|f-\varepsilon u\|^2=\|f\|^2-\varepsilon^2\|u\|^2-2\varepsilon\|G\|^2\le\|f\|^2.\]

A generalization is not a source correction. Proposed missing conditions require separate independent repair review. No proposed repair silently changes the original theorem.

Proof roadmap

All objects and hypotheses

Mathematical proof

1. Construct the original actual resolvent before choosing cutoffs

2. Derive linear drift and true scale-uniform cutoff bounds

3. Produce weighted L2 convergence through actual integrable squares

4. Control the drift commutator without an extra position moment

5. Derive simultaneous actual localized gradient/generator limits

6. Apply actual compact coercivity and pass both squared norms

7. Test the SAME variational equation at u
