Lemma 3.29.

We may choose the above holomorphic coordinates {wi}i=1n−1\{w_{i}\}_{i=1}^{n-1} centered at pp, so that HH is given by w1=0w_{1}=0 and

(3.318) ωD=−12​gi​j¯​d​wi∧d​w¯j,\omega_{D}=\frac{\sqrt{-1}}{2}g_{i\bar{j}}dw_{i}\wedge d\bar{w}_{j},

where

(3.319) {gi​j¯​(0)=δi​j,1≤i,j≤n−1,∂w1gi​j¯​(0)=0,1≤i,j≤n−1,∂wkg1​1¯​(0)=∂wkgi​j¯​(0)=0,2≤i,j,k≤n−1.\displaystyle\begin{cases}g_{i\bar{j}}(0)=\delta_{ij},&1\leq i,j\leq n-1,\\ \partial_{w_{1}}g_{i\bar{j}}(0)=0,&1\leq i,j\leq n-1,\\ \partial_{w_{k}}g_{1\bar{1}}(0)=\partial_{w_{k}}g_{i\bar{j}}(0)=0,&2\leq i,j,k\leq n-1.\end{cases}
