Half-space type theorems in warped product spaces with one-dimensional factor

摘要

This work states some half-space type theorems in a warped product space of the form I x _p M, where I e R is an open interval and M is either a compact n-manifold, or a complete simply connected surface with constant curvature c < 0. Such theorems generalize the classical half-space theorem for minimal surfaces in R3, obtained by Hoffmann and Meeks (Invent Math 101:373-377, 1990), and recent results for surfaces contained in a slab of R x p M, obtained by Dajczer and Alfas (Comment Math Helvetici 81:653-663, 2006).
