$α$ -高斯曲率流

$α$-Gauss Curvature flows

Lami Kim, Ki-ahm Lee

摘要:

本文研究了$\mathbb R^{n+1}$中n维严格凸超曲面的形变,其形变速度与高斯曲率正部分的$α$ -幂成正比.对于$\frac{1}{n}<α\leq 1$,证明了当初始曲面是严格凸光滑的且解超曲面收敛于一点时,存在严格凸光滑解.我们还证明了重标度超曲面的渐近性质,即重标度流形收敛到一个严格凸光滑流形。此外,存在一个子序列,其极限满足一定的方程。

英文摘要:

In this paper, we study the deformation of the n-dimensional strictly convex hypersurface in $\mathbb R^{n+1}$ whose speed at a point on the hypersurface is proportional to $α$-power of positive part of Gauss Curvature. For $\frac{1}{n}<α\leq 1$, we prove that there exist the strictly convex smooth solutions if the initial surface is strictly convex and smooth and the solution hypersurfaces converge to a point. We also show the asymptotic behavior of the rescaled hypersurfaces, in other words, the rescaled manifold converges to a strictly convex smooth manifold. Moreover, there exists a subsequence whose the limit satisfies a certain equation.
