Corollary 4.6.

Let ff be a smooth function on the Tian-Yau space satisfying the fast decay

|∇T​Ykf|=O⁡(e−c​rD1n−1n),∀k≥0,|\nabla_{TY}^{k}f|=O(e^{-cr_{D_{1}}^{\frac{n-1}{n}}}),\quad\forall k\geq 0,

then there is a smooth function UU with ΔT​Y​U=f\Delta_{TY}U=f in the form

U=const⋅u0+U~,|∇T​YkU|=O⁡(e−c​rD1n−1n),∀k≥0,U=\text{const}\cdot u_{0}+\tilde{U},\quad|\nabla_{TY}^{k}U|=O(e^{-cr_{D_{1}}^{\frac{n-1}{n}}}),\quad\forall k\geq 0,

for some possibly shrinked c>0c>0.
