Abstract

In this paper, we study a boundary blow-up problem for real (N1)(N-1)-Monge-Amp\`{e}re equations of the form \begin{equation} \nonumber \left \{ \begin{aligned} & \operatorname{\det}^{\frac{1}{N-1}}\left(\Delta zI-D^{2}z\right)=K(|x|)f(z) && \text{ in } \Omega, & z(x) \to \infty \text{ as } \dist(x,\partial\Omega) \to 0, \end{aligned} \right. \end{equation} where Ω\Omega denotes a ball in RN (N2)\mathbb{R}^{N} ~ (N \geq 2). The weight function KK is allowed to be singular, and the nonlinearity ff is assumed to satisfy a Keller-Osserman type condition. We establish the existence of infinitely many radial (N1)(N-1)-convex solutions to the system by employing the method of sub- and super-solutions, in conjunction with a comparison principle.
