Abstract

We prove a Gannon-Lee theorem for non-globally hyperbolic Lo\-rentzian metrics of regularity C1C^1, the most general regularity class currently available in the context of the classical singularity theorems. Along the way we also prove that any maximizing causal curve in a C1C^1-spacetime is a geodesic and hence of C2C^2-regularity.
