本文证明了任意维度下修正Mullins-Sekerka流的动力学稳定性:初始集合若与严格稳定临界集同体积且足够接近,则流全局存在并指数收敛到其平移,证明基于定量Alexandrov型估计。
AI 中文摘要
我们证明了在任意维度下修正Mullins-Sekerka流的动力学稳定性,该流是平坦环面上尖锐界面Ohta-Kawasaki能量的梯度流。具体而言,我们表明,如果初始集合与能量的严格稳定临界集具有相同体积,并且在$C^{3,\alpha}$范数下足够接近该临界集,则该流对所有时间存在,并以指数速度在每个$C^k$范数下收敛到该临界集的平移。证明依赖于对能量严格稳定临界集的定量Alexandrov型估计。
英文摘要
We prove dynamical stability in arbitrary dimension for the modified Mullins--Sekerka flow, the gradient flow of the sharp-interface Ohta--Kawasaki energy on the flat torus. Specifically, we show that if an initial set has the same volume as a strictly stable critical set for the energy and is sufficiently close to it in $C^{3,α}$, then the flow exists for all times and converges exponentially fast, in every $C^k$ norm, to a translate of that critical set. The proof relies on a quantitative Alexandrov-type estimate for strictly stable critical sets of the energy.
