We estimate from above the rate at which a solution to the normalized Ricci flow on a closed manifold may converge to a limit soliton. Our main result implies that any solution which converges modulo diffeomorphisms to a soliton faster than any fixed exponential rate must itself be self-similar.

关于 Ricci 流下的最大收敛率

我们从上面估计了封闭流形上归一化 Ricci 流的解可能收敛到极限孤子的速率。我们的主要结果意味着，任何将模微分同胚收敛到孤子的速度比任何固定指数速率更快的解决方案本身必须是自相似的。
