I have a technical question :
Consider the triple $(M,D,\omega)$ where $M$ is a Fano manifold, $D$ is a smooth divisor whose Poincare dual is $\lambda c_1(M)$ and $\omega$ is a conic Kaehler -Einstein metric on $M$ with cone angle $2\pi\beta$ along $D$. Let $S$ is a difining section of $D$ . In local holomorphic coordinates $z_1,z_2,...,z_n$ , write $S=f\big(\frac{\partial}{\partial z_1}\wedge...\wedge \frac{\partial}{\partial z_n}\big)$ and $H(.,.)$ be a Hermitian metric on $K_M^{-1}$ and $\omega=i\sum g_{\alpha\bar\beta}dz_\alpha\wedge d\bar z_\beta$
then $H$ can be represented by
$$\text{det}(g_{\alpha\bar\beta})^{\frac{1}{\mu}}\mid f \mid^{\frac{2(1-\beta)}{\mu}}$$
for some $\mu$
This fact has been appeared in most of the papers about Kahler-Einstein metrics. But I am looking for a reason!
See this paper for details
