Fengrui Yang

摘要:

给定曲率测度问题是微分几何和非线性偏微分方程中的重要问题之一。本文考虑双曲空间中的规定曲率测度问题。在双曲空间中,通过对相应的完全非线性偏微分方程的解建立关键的C^2正则性估计,得到了具有指定的(n-k)阶曲率测度(k<n)的星形k-凸体的存在性.

英文摘要:

The problem of the prescribed curvature measure is one of the important problems in differential geometry and nonlinear partial differential equations. In this paper, we consider prescribed curvature measure problem in hyperbolic space. We obtain the existence of star-shaped k-convex bodies with prescribed (n-k)-th curvature measures (k<n) by establishing crucial C^2 regularity estimates for solutions to the corresponding fully nonlinear PDE in the hyperbolic space.
