The codimension 2 null cut locus with applications to spacetime topology (2205.11391v2)
Published 23 May 2022 in gr-qc and math.DG
Abstract: In this paper we review and extend some results in the literature pertaining to spacetime topology while naturally utilizing properties of the codimension 2 null cut locus. Our results fall into two classes, depending on whether or not one assumes the presence of horizons. Included among the spacetimes we consider are those that apply to the asymptotically (locally) AdS setting.
