Entire subsolutions of a kind of k-Hessian type equations with gradient terms

Jingwen Ji, Feida Jiang, Mengni Li

In this paper, we consider a kind of $k$ -Hessian type equations $S_{k}^{\frac{1}{k}} (D^{2} u + μ ∣ D u ∣ I) = f (u)$ in $R^{n}$ , and provide a necessary and sufficient condition of $f$ o…

On the solutions to weakly coupled system of $k_{i}$ -Hessian equations

Jingwen Ji, Feida Jiang, Baohua Dong

In this paper, the existence and multiplicity of nontrivial radial convex solutions to general coupled system of $k_{i}$ -Hessian equations in a unit ball are studied via a fixed-poin…

On the Dirichlet problem for a class of augmented Hessian equations

Feida Jiang, Neil S. Trudinger, Xiao-Ping Yang

In this paper, we consider the Dirichlet problem for a new class of augmented Hessian equations. Under sharp assumptions that the matrix function in the augmented Hessian is regula…
