论文摘要
对于任何具有正曲率的3D稳定梯度RICCI Soliton,我们证明,如果它对射线渐近,则必须对Bryant Soliton等静脉测定。否则,它对一个部门渐近,因此是飞行翼。我们证明所有3D飞行翅膀均为O(2) - 对称。因此,所有3D稳定的梯度RICCI唯一均为O(2) - 对称。
For any 3D steady gradient Ricci soliton with positive curvature, we prove that it must be isometric to the Bryant soliton if it is asymptotic to a ray. Otherwise, it is asymptotic to a sector and hence a flying wing. We show that all 3D flying wings are O(2)-symmetric. Therefore, all 3D steady gradient Ricci solitons are O(2)-symmetric.
