Rotationally symmetric solutions of the prescribed higher mean curvature spacelike equations in Minkowski spacetime

다국어 초록 (Multilingual Abstract)

In this paper we consider the existence of rotationally symmetric entire solutions for the prescribed higher mean curvature spacelike equations in Minkowski spacetime. As a first step, we study the associated 0-Dirichlet problems on a ball, and then we prove that all possible solutions can be extended to $+\infty$. The proof of our main results are based upon the topological degree methods and the standard prolongability theorem of ordinary differential equations.
