Special Standard Static Space-Times
(Pergamon-elsevier Science Ltd, 2004) Dobarro, F; Ünal, B
Essentially, some conditions for the Riemannian factor and the warping function of a standard static space-time are obtained in order to guarantee that no nontrivial warping function on the Riemannian factor can make the standard static space-time Einstein.

The Local Mobius Equation and Decomposition Theorems in Riemannian Geometry
(Canadian Mathematical Soc, 2002) Fernández-López, M; García-Río, E; Kupeli, DN
A partial differential equation, the local Mobius equation, is introduced in Riemannian geometry which completely characterizes the local twisted product structure of a Riemannian manifold. Also the characterizations of warped product and product structures of Riemannian manifolds are made by the local Mobius equation and an additional partial differential equation.
