Brendle在最近的一篇论文中证明了三维κ-解中Bryant孤子的唯一性。在本文中,我们提出了一个替代的证明这一事实,并表明,紧κ-解是旋转对称的。我们的证明产生于独立的工作,我们的强稳定性定理奇异里奇流。
Abstract In a recent paper, Brendle showed the uniqueness of the Bryant soliton among 3-dimensional κ-solutions. In this paper, we present an alternative proof for this fact and show that compact κ-solutions are rotationally symmetric. Our proof arose from independent work relating to our Strong Stability Theorem for singular Ricci flows.
