Popis: We provide a generalization of global hyperbolicity in pseudo-Riemannian spaces of signature $(p, q)$ for $p \ge q \ge 2$. We then prove the compactness of causal diamonds in globally hyperbolic spaces and deduce the existence of solutions to a Plateau problem for this class of spaces. Finally, we describe the topology of globally hyperbolic spaces in a result generalising Geroch's splitting theorem.
