The $L_{p}$ dual Christoffel-Minkowski type problem for a class of Hessian quotient equations

Shasha Luo, Jiabao Gong, Qiang Tu

In this paper, we investigate an $L_{p}$ dual Christoffel-Minkowski type problem for the Hessian quotient operator $\frac{I ¨ _{k} ( I ^ )}{I ¨ _{l} ( I ^ )}$ , where the operator $I^$ has been w…

The Neumann problem for a class of degenerate Hessian quotient type equations

Jiabao Gong, Qiang Tu

In this paper, we obtain some important inequalities for a class of Hessian quotient type operators $\frac{I ¨ _{k} ( I ^ ( D ^{2} u ))}{I ¨ _{l} ( I ^ ( D ^{2} u ))}$ , which can be regarded as a generalizati…

Second order estimates for $I ¨ $ -semi convex solutions of Hessian equations on Hermitian manifolds

Xiaojuan Chen, Qiang Tu, Ni Xiang

In this paper, we establish the modified concavity inequality for complex Hessian equations under the semi-convexity assumption inspired by Lu \cite{Lu23} and Zhang \cite{Z24} for…
