On the Geometry of Conformally Stationary Lorentz Spaces
F. Camargo, A. Caminha, H. de Lima +1
In this paper we study several aspects of the geometry of conformally stationary Lorentz manifolds, and particularly of GRW spaces, due to the presence of a closed conformal vector…

-Stable Hypersurfaces in Conformally Stationary Spacetimes
F. Camargo, A. Caminha, H. de Lima +1
In this paper we study the r-stability of closed spacelike hypersurfaces with constant -th mean curvature in conformally stationary spacetimes of constant sectional curvature. I…
