# Weil-Petersson metric is quasi isometric with which model?

Let $\mathcal M_g$ be the moduli space of curves of genus $g$. If we take $X^{reg}=X\setminus D$, where D is a divisor with normal crossings. Endow $X^{reg}$ with a complete Kahler metric which has a type of singularities normal to each component of $D$; in local coordinates, if $D = (z_1,...,z_k)$, the Weil-Petersson metric on moduli space of $\mathcal M_g$ is quasi-isometric with the following model, $$\sum_{i=1}^k\frac{dz_i\wedge d\bar z_i}{|z_i|^2(-\log |z_i|)^3}+\sum_{i=k+1}^n dz_i\wedge d\bar z_i$$

Let $\omega_{WP}$ be the Weil-Petersson metric on moduli space of Calabi-Yau varieties, then $\omega_{WP}$ is quasi-isometric with which model?

$$\omega_{WP}=\left\{\frac{\ell }{|s|^2(\log |s|)^2}+O\left(\frac{1 }{|s|^2(\log |s|)^3}\right)\right\}\sqrt[]{-1}ds\wedge d\bar s$$
