摘要
我们证明了 上共形于平坦度量、具有几乎恒定正标量曲率且不能集中多于一个气泡的度量的定量结构定理。作为我们结果的一个应用,我们给出了 中与 Yamabe 流相关的快速扩散方程在相对熵下的定量收敛速率。

备注
Because of a gap in one proof in the previous version, we replaced the paper with a weaker version of our Theorem 1.1. Still, this result suffices to obtain the main conclusion in the previous paper, namely a quantitative convergence estimate for a fast diffusion equation related to the Yamabe flow
