Generalized cones as Lorentzian length spaces: Causality, curvature, and singularity theorems

Stephanie B. Alexander, Melanie Graf, Michael Kunzinger +1

We study generalizations of Lorentzian warped products with one-dimensional base of the form $I{\times }_{f}X$, where $I$ is an interval, $X$ is a length space and $f$ is a positive co…
