Pogorelov type estimates for a class of Hessian quotient equations in Lorentz-Minkowski space ${\mathbb{R}}_1^{n+1}$

Chenyang Liu, Jing Mao, Yating Zhao

Let $\Omega$ be a bounded domain (with smooth boundary) on the hyperbolic plane ${\mathcal{H}}^n(1)$, of center at origin and radius $1$, in the $(n+1)$-dimensional Lorentz-Minkowski sp…
