摘要

曲率测度问题是微分几何和非线性偏微分方程中的一个重要问题。本文考虑双曲空间中的曲率测度问题。通过对双曲空间中相应的全非线性PDE的解建立关键的C2正则性估计，我们获得了具有规定曲率测度的星形k凸体的存在性。

Prescribed curvature measure problem in hyperbolic space

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 the prescribed curvature measure problem in the hyperbolic space. We obtain the existence of star-shaped k-convex bodies with prescribed (n-k)-th curvature measures $(k < n)$ by establishing crucial C² regularity estimates for solutions to the corresponding fully nonlinear PDE in the hyperbolic space.
