摘要:
我们证明了几何偏微分方程中几个结果的定量版本。首先,我们得到了空间形式中 Serrin 超定问题的双重稳定性定理。其次,我们在一类扭曲积空间中分别证明了 Brendle 的 Heintze-Karcher 不等式与常平均曲率分类的稳定性定理。关键工具是第一作者近期关于函数水平集在无迹 Hessian 微小性下稳定性的研究。
英文摘要:
We prove quantitative versions for several results from geometric partial differential equations. Firstly, we obtain a double stability theorem for Serrin's overdetermined problem in spaceforms. Secondly, we prove stability theorems for Brendle's Heintze-Karcher inequality respectively constant mean curvature classification in a class of warped product spaces. The key tool is the first author's recent development of stability for level sets of a function under smallness of the traceless Hessian thereof.
