双曲空间中的内曲率估计与渐近坪问题

Interior curvature estimates and the asymptotic plateau problem in hyperbolic space

Bo Guan, Joel Spruck, Ling Xiao

摘要:

我们证明了对于一类定义在正锥上的曲率函数,在满足$f(κ)=σ\in(0, 1)$且在无穷远处有一个渐近边界$Γ$的$H^n+1$中寻找一个完备的严格局部凸超曲面的问题至少有一个光滑解,其主曲率为双曲主曲率.此外,如果$Γ$是(欧几里德)星形的,则解是唯一的,并且也是(欧几里德)星形的,而如果$Γ$是平均凸的,则解是唯一的。我们还通过一个强对偶定理证明了类似的结果在De Sitter空间中也成立。我们的方法的一个新功能是“全球内部曲率估计”。

英文摘要:

We show that for a very general class of curvature functions defined in the positive cone, the problem of finding a complete strictly locally convex hypersurface in $H^n+1$ satisfying $f(κ)=σ\in(0, 1)$ with a prescribed asymptotic boundary $Γ$ at infinity has at least one smooth solution with uniformly bounded hyperbolic principal curvatures. Moreover if $Γ$ is (Euclidean) starshaped, the solution is unique and also (Euclidean) starshaped while if $Γ$ is mean convex the solution is unique. We also show via a strong duality theorem that analogous results hold in De Sitter space. A novel feature of our approach is a "global interior curvature estimate".
