A generalization of Newton-Maclaurin's inequalities

Changyu Ren

In this paper, we prove Newton-Maclaurin type inequalities for functions obtained by linear combination of two neighboring primary symmetry functions, which is a generalization of…

Pogorelov type $C^{2}$ estimates for Sum Hessian equations and a rigidity theorem

Yue Liu, Changyu Ren

We mainly study Pogorelov type $C^{2}$ estimates for solutions to the Dirichlet problem of Sum Hessian equations. We establish respectively Pogorelov type $C^{2}$ estimates for $k$ -con…
