چکیده
The aim of the present paper is to obtain condition under which a pseudosymmetric spacetime be perfect fluid spacetime. It proven that generalized Robertson-Walker Moreover, we establish conformally flat Next, it shown dust with constant scalar curvature satisfying Einstein's field equations without cosmological vacuum. Finally, construct non-trivial example

Spacetime encodings. I. A spacetime reconstruction problem
This paper explores features of an idealized mathematical machine (algorithm) that would be capable of reconstructing the gravitational nature (the multipolar structure or spacetime metric) of a compact object, by observing gravitational radiation emitted by a small object that orbits and spirals into it. An outline is given of the mathematical developments that must be carried out in order to ...
متن کاملHydrostatic Equilibrium of a Perfect Fluid Sphere with Exterior Higher Dimensional Schwarzschild Spacetime
We discuss the question of how the number of dimensions of space and time can influence the equilibrium configurations of stars. We find that dimensionality does increase the effect of mass but not the contribution of the pressure, which is the same in any dimension. In the presence of a (positive) cosmological constant the condition of hydrostatic equilibrium imposes a lower limit on mass and ...
متن کاملCan electro - magnetic field , anisotropic source and varying Λ be sufficient to produce wormhole spacetime ?
It is well known that solutions of general relativity which allow for traversable wormholes require the existence of exotic matter ( matter that violates weak or null energy conditions [WEC or NEC] ). So to construct wormholes theoretically without breaking NEC or WEC remains an elusive goal to the theoretical physicists. In this article, we provide a class of exact solution for Einstein-Maxwel...
متن کاملQuantum Spacetime: a Disambiguation
We review an approach to non-commutative geometry, where models are constructed by quantisation of the coordinates. In particular we focus on the full DFR model and its irreducible components; the (arbitrary) restriction to a particular irreducible component is often referred to as the“canonical quantum spacetime”. The aim is to distinguish and compare the approaches under various points of vie...
متن کاملSpacetime geometry of static fluid spheres
We exhibit a simple and explicit formula for the metric of an arbitrary static spherically symmetric perfect fluid spacetime. This class of metrics depends on one freely specifiable monotone non-increasing generating function. We also investigate various regularity conditions, and the constraints they impose. Because we never make any assumptions as to the nature (or even the existence) of an e...
