Interior Hessian estimates for Hessian quotient equations in dimension three

Heming Jiao, Zhenan Sui

In this paper, we establish the interior Hessian estimates for $2$ -convex solutions to $\frac{I ¨ _{2}}{I ¨ _{1}} (D^{2} u) = I ¨ (x, u)$ in dimension three. In higher dimensions ( $n \geq 4$ ),…

Asymptotic Plateau problem for $3$ -convex hypersurface in $H^{5}$

Zhenan Sui

We prove the existence of a smooth complete $3$ -convex hypersurface which satisfies prescribed curvature equation $i = 1 \prod n (H - I^º_{i}) = ((n - 1) I ¨ )^{n}$ for…

Existence of solution to modified Gursky-Streets equation

Yi Huang, Zhenan Sui, Mingyu Xie

We solve the modified Gursky-Streets equation, which is a fully nonlinear equation arising in conformal geometry with uniform $C^{1, 1}$ estimates when (i) $I^^{3} > 0$ and $1 \leq k \l…
