Constant mean curvature spacelike hypersurfaces in spatially open GRW spacetimes (2107.13906v1)
Published 29 Jul 2021 in math.DG
Abstract: In this paper we provide under certain geometric and physical assumptions new uniqueness and non-existence results for complete spacelike hypersurfaces of constant mean curvature in spatially open Generalized Robertson-Walker spacetimes. Some of our results are then applied to relevant spacetimes as the steady state spacetime, Einstein-de Sitter spacetime and certain radiation models.
