Boundary blow-up solutions to real $(N-1)$-Monge-Ampère equations with singular weights (2511.12091v1)

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