欧几里得空间中平稳等温曲面的对称性问题
Symmetry problems on stationary isothermic surfaces in Euclidean spaces
摘要:
设$S$是一个光滑超曲面,它以$N \geq 3$嵌入$\mathbb R^N$中,并考虑它的管状邻域$\mathcal N$ .我们表明,如果热流过$\mathcal N$与适当的初始和边界条件有$S$作为一个固定的等温表面,那么$S$必须有某种对称性。
英文摘要:
Let $S$ be a smooth hypersurface properly embedded in $\mathbb R^N$ with $N \geq 3$ and consider its tubular neighborhood $\mathcal N$. We show that, if a heat flow over $\mathcal N$ with appropriate initial and boundary conditions has $S$ as a stationary isothermic surface, then $S$ must have some sort of symmetry.
