On holonomy singularities in general relativity and the C0,1loc-inextendibility of spacetimes

Abstract / Description of output

This paper investigates the structure of gravitational singularities at the level of the connection. We show in particular that for FLRW spacetimes with particle horizons a local holonomy, which is related to a gravitational energy, becomes unbounded near the big-bang singularity. This implies the C0,1loc-inextendibility of such FLRW spacetimes. Again using an unbounded local holonomy we also give a general theorem establishing the C0,1loc-inextendibility of spherically symmetric weak null singularities which arise at the Cauchy horizon in the interior of black holes. Our theorem does not presuppose the mass-inflation scenario and in particular applies to the Reissner-Nordström-Vaidya spacetimes as well as to spacetimes which arise from small and generic spherically symmetric perturbations of two-ended subextremal Reissner-Nordström initial data for the Einstein-Maxwell-scalar field system. In [26], [27] Luk and Oh proved the C2-formulation of strong cosmic censorship for this latter class of spacetimes -- and based on their work we improve this to a C0,1loc-formulation of strong cosmic censorship.
