Entire spacelike hypersurfaces of prescribed Gauss curvature in Minkowski space. (English) Zbl 1097.53040
The paper deals with space-like convex hypersurfaces of positive constant (K-hypersurfaces) or prescribed Gauss curvature in Minkowski space $$\mathbb R_1^n$$ where $$n \geq 2.$$ More explicitly, the authors study the entire solutions on $$\mathbb R^n$$ of the Monge-Ampère equation: $\text{ det} D^2 u = \psi(x,u)(1-| Du| ^2)^{\frac{n+2}{2}}$ with the space-like condition $| Du| <1,$ because each of these hypersurfaces can be expressed as the graph of a convex function $$x_{n+1}=u(x)$$ satisfying the Monge-Ampère equation and the space-like condition where $$\psi$$ is the Gauss curvature.
The authors provide a classification for entire space-like K-hypersurfaces admitting a rotational symmetry with respect to a space-like axis. They are also interested in determining entire K-hypersurfaces in Minkowski space with bounded Gauss curvature admitting a prescribed tangent cone at infinity.
Moreover, the Minkowski type problem is considered due to its close relation to the problem of finding entire space-like hypersurfaces with prescribed Gauss curvature and extensions of some of the results in [A.-M. Li, Arch. Math. 64, No. 6, 534–551 (1995; Zbl 0828.53050)] are obtained.
