In this paper we generalize a
well-known result of Frankel which relates the fundamental group of a complete
Riemannian manifold with positive Ricci curvature to the fundamental group of a
compact immersed minimal hypersurface. Here we consider the situation in which the
Ricci curvature of the ambient manifold is only assumed to be nonnegative, and
show that the conclusion of Frankel’s theorem can fail only under special
circumstances.
