Causality and c-completion of multiwarped spacetimes
L. Aké Hau, J. L. Flores, J. Herrera
In this paper a systematic study of the causal structure and global causality properties of multiwarped spacetimes is developed. This analysis is used to make a detailed descriptio…

Rigidity of geodesic completeness in the Brinkmann class of gravitational wave spacetimes
Ivan P. Costa e Silva, Jose Luis Flores, Jonatan Herrera
We consider restrictions placed by geodesic completeness on spacetimes possessing a null parallel vector field, the so-called Brinkmann spacetimes. This class of spacetimes include…

On a monodromy theorem for sheaves of local fields and applications
Jonatan Herrera, Miguel Angel Javaloyes, Paolo Piccione
We prove a monodromy theorem for local vector fields belonging to a sheaf satisfying the unique continuation property. In particular, in the case of admissible regular sheaves of l…
