变分无穷大基态的刚性结果

Rigidity results for variational infinity ground states

Graziano Crasta, Ilaria Fragalà

摘要:

本文证明了开有界凸区域$Ω\subset \mathbb{R}^n$的变分无穷基态$u$的两个刚性结果。他们指出,如果$|\nabla u|$在$\partial Ω$上是常数,或者$u$属于$Ω$高脊之外的$C ^ {1,1}$类,则$u$与距离$Ω$边界的距离的倍数一致。因此,在这两种情况下,$Ω$可以在几何学上表征为“体育场样结构域”。

英文摘要:

We prove two rigidity results for a variational infinity ground state $u$ of an open bounded convex domain $Ω\subset \mathbb{R}^n$. They state that $u$ coincides with a multiple of the distance from the boundary of $Ω$ if either $|\nabla u|$ is constant on $\partial Ω$, or $u$ is of class $C ^ {1,1}$ outside the high ridge of $Ω$. Consequently, in both cases $Ω$ can be geometrically characterized as a "stadium-like domain".
