Theorem 4.2.

[16][10, Prop. 2.9] There is a complete Ricci-flat Kähler metric

ωT​Y=d​dc​ϕT​Y=ωC​a​l′+d​dc​ϕT​Y,r​e​l\omega_{TY}=dd^{c}\phi_{TY}=\omega_{Cal^{\prime}}+dd^{c}\phi_{TY,rel}

solving the complex Monge-Ampère equation

ωT​Yn−1=d2n−2​∫Yc1​(L0)n−24​π​−1(n−1)2​ΩD1∧Ω¯D1,\omega_{TY}^{n-1}=\frac{d_{2}^{n-2}\int_{Y}c_{1}(L_{0})^{n-2}}{4\pi}\sqrt{-1}^{(n-1)^{2}}\Omega_{D_{1}}\wedge\overline{\Omega}_{D_{1}},

with exponential decay estimate for some constant c>0c>0 depending on D1,D2D_{1},D_{2}:

|∇ωC​a​l′kϕT​Y,r​e​l|ωC​a​l′=O⁡(e−c​rD1n−1n),rD1→+∞,k≥0.|\nabla_{\omega_{Cal^{\prime}}}^{k}\phi_{TY,rel}|_{\omega_{Cal^{\prime}}}=O(e^{-cr_{D_{1}}^{\frac{n-1}{n}}}),\quad r_{D_{1}}\to+\infty,\quad k\geq 0.
