AI 中文摘要
本文研究一类 Hessian 曲率方程的闭的、星形超曲面的存在性。通过将先验估计与连续性方法相结合,我们建立了非齐次和齐次 Hessian 曲率方程的 k - 凸超曲面的存在性和唯一性。通过建立一个常秩定理,我们证明了所得的 k - 凸超曲面是严格凸的。
英文摘要
This article investigates the existence of closed, star-shaped hypersurfaces for a class of Hessian curvature equations. By combining a priori estimates with the continuity method, we establish the existence and uniqueness of $k$-convex hypersurfaces for both nonhomogeneous and homogeneous Hessian curvature equations, and by establishing a constant rank theorem, we prove that the resulting $k$-convex hypersurfaces are strictly convex.
