我们证明了在\mathbb R^3中光滑闭嵌入严格凸曲面沿平均曲率流时,Willmore亏量\int_{\Sigma}H^2\\,d\mu-16\pi的晚期单调性,这细化了Huisken给出的指数收敛结果。作为推论,Hawking质量沿平均曲率流最终非递减。我们还讨论了三维空间形式中的全脐解,其中Willmore能量和Hawking质量的单调性方向取决于环境截面曲率的符号。
英文摘要
We prove a late-time monotonicity of the Willmore deficit \(\int_ΣH^2\,dμ-16π\) along the mean curvature flow of smooth closed embedded strictly convex surfaces in \(\mathbb R^3\),which refining the exponential convergence given by Huisken. As a consequence, the Hawking mass is eventually non--decreasing along mean curvature flow. We also discuss totally umbilical solutions in three-dimensional space forms, where the monotonicity directions of the Willmore energy and the Hawking mass depend on the sign of the ambient sectional curvature.
