چکیده
In this paper we characterize weakly Ricci-symmetric spacetimes (WRS)n endowed with the Gray?s Decomposition. We provide, several interesting results of in addition discuss some based on Generalized Robertson Walker (GRW) spacetimes. Moreover, study which satisfy f (R, T)-gravity equation.

Surface gravity in dynamical spherically symmetric spacetimes.
A definition of surface gravity at the apparent horizon of dynamical spherically symmetric spacetimes is proposed. It is based on a unique foliation by ingoing null hypersurfaces. The function parametrizing the hypersurfaces can be interpreted as the phase of a light wave uniformly emitted by some faraway static observer. The definition gives back the accepted value of surface gravity in the st...
متن کاملOn Conharmonically and Special Weakly Ricci Symmetric Sasakian Manifolds
We have studied some geometric properties of conharmonically flat Sasakian manifold and an Einstein-Sasakian manifold satisfying R(X, Y ).N = 0. We have also obtained some results on special weakly Ricci symmetric Sasakian manifold and have shown that it is an Einstein manifold. AMS Mathematics Subject Classification (2000): 53C21, 53C25

متن کاملPseudo Ricci symmetric real hypersurfaces of a complex projective space
Pseudo Ricci symmetric real hypersurfaces of a complex projective space are classified and it is proved that there are no pseudo Ricci symmetric real hypersurfaces of the complex projective space CPn for which the vector field ξ from the almost contact metric structure (φ, ξ, η, g) is a principal curvature vector field.
متن کاملRicci Flow Gravity
A theory of gravitation is proposed, modeled after the notion of a Ricci flow. In addition to the metric an independent volume enters as a fundamental geometric structure. Einstein gravity is included as a limiting case. Despite being a scalar-tensor theory the coupling to matter is different from Jordan-Brans-Dicke gravity. In particular there is no adjustable coupling constant. For the solar ...
