Abstract

Let U B(p 0; ρ 1) × f M V be a cylindrically bounded domain in a warped product manifold := M B × f M V and let M be an isometrically immersed submanifold in . The purpose of this paper is to provide explicit radii of the geodesic balls of M which first exit from U B(p 0; ρ 1) × f M V for the case in which the mean curvature of M is sufficiently small and the lower bound of the Ricci curvature of M does not diverge to –∞ too rapidly at infinity.
