On the fundamental group of a complete globally hyperbolic Lorentzian manifold with a lower bound for the curvature tensor

Jun-ichi Mukuno

Published 2014-09-03Version 1

In this paper, we study the fundamental group of a certain class of globally hyperbolic Lorentzian manifolds with a positive curvature tensor. We prove that the fundamental group of lightlike geodesically complete parametrized Lorentzian products is finite under the conditions of a positive curvature tensor and the fiber compact.
