3.7.4. Global weighted Hölder norms and error estimates

Now we introduce the global weighted Hölder norms ‖⋅‖Cδk,α\left\lVert\cdot\right\rVert_{C^{k,\alpha}_{\delta}} on Mν+M^{+}_{\nu} by demanding that up to uniform equivalence the norm is

  • •

    ‖⋅‖Cδk,α\left\lVert\cdot\right\rVert_{C^{k,\alpha}_{\delta}} on M+∩{|μ→|a≳A−1/4}M^{+}\cap\{|\vec{\mu}|_{a}\gtrsim A^{-1/4}\}, as defined in Section 3.4.

  • •

    ‖⋅‖Ck,αδ,0(ℂ3∩{|μ→|a≤13A1/2})\left\lVert\cdot\right\rVert_{C^{k,\alpha}_{\delta,0}(\mathbb{C}^{3}\cap\{|\vec{\mu}|_{a}\leq\frac{1}{3}A^{1/2}\})} on ℂ3\mathbb{C}^{3} for |μ→|a≤13​A1/2|\vec{\mu}|_{a}\leq\frac{1}{3}A^{1/2}.

On overlapping regions the definitions are equivalent.

Proposition 3.31.

On Mν+M^{+}_{\nu} the volume form error satisfies the estimate

(3.11) ‖E~(4)‖C−1−ϵk,α≤C​A3/4​(−1+ϵ)​ν2.\left\lVert\tilde{E}^{(4)}\right\rVert_{C^{k,\alpha}_{-1-\epsilon}}\leq CA^{3/4(-1+\epsilon)}\nu^{2}.
Proof.

Combine Lemma 3.30 with Corollary 3.24. ∎
