中曲率流的极小锥和自展开解

Minimal cones and self-expanding solutions for mean curvature flows

Qi Ding

摘要:

本文研究了欧几里得空间中中曲率流的自扩张解及其与极小锥的关系。在[18]中,Ilmanen证明了在无穷远处具有预定切锥的自膨胀超曲面的存在性。如果锥是$C^{3,α}$ -正则且平均凸的(但不是面积最小的),我们可以证明相应的自膨胀超曲面是光滑的,嵌入的,并且处处具有正的中曲率(见定理1.1)。因此,对于正则极小锥而不是面积极小锥,我们可以肯定地回答Lawson [4]提出的一个问题。

英文摘要:

In this paper, we study self-expanding solutions for mean curvature flows and their relationship to minimal cones in Euclidean space. In [18], Ilmanen proved the existence of self-expanding hypersurfaces with prescribed tangent cones at infinity. If the cone is $C^{3,α}$-regular and mean convex (but not area-minimizing), we can prove that the corresponding self-expanding hypersurfaces are smooth, embedded, and have positive mean curvature everywhere (see Theorem 1.1). As a result, for regular minimal but not area-minimizing cones we can give an affirmative answer to a problem arisen by Lawson [4].
