Interior Hessian estimates for sum Hessian quotient equation

Changyu Ren, Ziyi Wang

This paper is devoted to the interior $C^{2}$ estimates for a class of sum Hessian quotient equations. For $0 \leq l < k < n$ , we establish the interior estimates and the Pogorelov type e…

Pogorelov type $C^{2}$ estimates for sum Hessian equations

Pengfei Li, Changyu Ren

In this paper, We establish Pogorelov type $C^{2}$ estimates for the admissible solutions with $I ¨ _{k} (D^{2} u)$ bounded from below of Sum Hessian equations. We also proved the lower boun…
