A Moser-Bernstein problem for Riemannian warped products

Abstract

In this work we deal with an elliptic non-linear problem, which arises naturally from Riemannian geometry. This problem has clasically been studied in the the Euclidean $n$-dimensional space and it is known as the Moser-Bernstein problem. Nevertheless we solve this type of problems in a wide family of Riemannian manifolds, constructed as Riemannian warped products. More precicely, we study the entire solutions to the minimal hypersurface equation in a Riemannian warped product $M=P{\times }_h\mathbb{R}$, where $P$ is a complete Riemannian parabolic manifold and $h$ a positive smooth function on $P$.
