Lemma 4.9.

On |z|≥1|z|\geq 1, we have

(4.124) C−1​T(n−2)​(1−n)n​(T+k±​z)1−n​ω±,c​y​l≤ω≤C​T2−nn​(T+k±​z)⋅ω±,c​y​lC^{-1}T^{\frac{(n-2)(1-n)}{n}}(T+k_{\pm}z)^{1-n}\omega_{\pm,cyl}\leq\omega\leq CT^{\frac{2-n}{n}}(T+k_{\pm}z)\cdot\omega_{\pm,cyl}

and for all k≥1k\geq 1, there exists mk,Ckm_{k},C_{k} such that

(4.125) |∇ω±,c​y​lkω|ω±,c​y​l≤Ck​(T2−nn​(T+k±​z))mk.|\nabla^{k}_{\omega_{\pm,cyl}}\omega|_{\omega_{\pm,cyl}}\leq C_{k}(T^{\frac{2-n}{n}}(T+k_{\pm}z))^{m_{k}}.
