Proposition 4.23 (Weighted error estimate).

Let ErrC​Y\mathrm{Err}_{CY} be the error function given by Definition 4.3. For fixed parameters δ>0\delta>0, μ,ν∈ℝ\mu,\nu\in\mathbb{R} and α∈(0,1)\alpha\in(0,1) which satisfy

(4.304) 0<δ<δe\displaystyle 0<\delta<\delta_{e} ≡λ1n⁡(|k−|+|k+|),\displaystyle\equiv\frac{\sqrt{\lambda_{1}}}{n(|k_{-}|+|k_{+}|)},
(4.305) ν+α\displaystyle\nu+\alpha >0,\displaystyle>0,

where the constants λ1>0\lambda_{1}>0, k−>0k_{-}>0 and k+<0k_{+}<0 are given in Proposition 3.31. Then the weighted C0,αC^{0,\alpha}-estimate holds,

(4.306) ‖ErrC​Y‖Cδ,ν,μ0,α​(ℳT)=O⁡(T−2+ν+αn+μ).\|\mathrm{Err}_{CY}\|_{C^{0,\alpha}_{\delta,\nu,\mu}(\mathcal{M}_{T})}=O(T^{-2+\frac{\nu+\alpha}{n}+\mu}).
