Uniqueness of the critical points of solutions to two kinds of semilinear elliptic equations in higher dimensional domains

Haiyun Deng, Jingwen Ji, Feida Jiang +1

In this paper, we provide an affirmative answer to the {\it conjecture A} for bounded simple rotationally symmetric domains $Ω \subset R^{n} (n \geq 3)$ along $x_{n}$ axis. Preci…

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…
