加权柱体内带边界超曲面的唯一性结果和封闭性

Uniqueness results and enclosure properties for hypersurfaces with boundary in weighted cylinders

Katherine Castro, César Rosales

摘要:

对于一个黎曼流形$M$,可能有边界,我们考虑黎曼积$M\times\mathbb{R}^k$与一个光滑的正函数,加权黎曼测度。在这篇文章中,我们刻画了包含在$M\times\mathbb{R}^k$的某些区域内的具有非空边界的抛物超曲面。我们的结果包括半空间和Bernstein型定理加权柱。我们也推广到这个设置的一些经典性质的限制一个紧凑的极小超曲面的某些区域的欧几里得空间根据其边界的位置。最后,我们展示了有趣的情况下,其中的语句被应用,其中一些关系到的奇性的中曲率流。

英文摘要:

For a Riemannian manifold $M$, possibly with boundary, we consider the Riemannian product $M\times\mathbb{R}^k$ with a smooth positive function that weights the Riemannian measures. In this work we characterize parabolic hypersurfaces with non-empty boundary and contained within certain regions of $M\times\mathbb{R}^k$ with suitable weights. Our results include half-space and Bernstein-type theorems in weighted cylinders. We also generalize to this setting some classical properties about the confinement of a compact minimal hypersurface to certain regions of Euclidean space according to the position of its boundary. Finally, we show interesting situations where the statements are applied, some of them in relation to the singularities of the mean curvature flow.
