我们证明,直到孤子矢量场的流动,在卡拉比-丘锥体的等变绉纹分辨率的每个卡勒类中,都存在唯一的完全稳定梯度卡勒-里奇孤子,以多项式速率收敛到锥体上曹的稳定梯度卡勒-里奇孤子。
We show that, up to the flow of the soliton vector field, there exists a unique complete steady gradient Kahler-Ricci soliton in every Kahler class of an equivariant crepant resolution of a Calabi-Yau cone converging at a polynomial rate to Cao's steady gradient Kahler-Ricci soliton on the cone.
