چکیده
I1 is shown thal for a given spherically symmelric disvibution of a perfect Huid on a spacelike hypersurface wiul boundary and a piven. time-dependent boundary prt?sure. there exis15 a unique, local-in-lime solution of the Einstein equations. A Schwmchild spacetime can be allached to h e Huid bady i f and only if the boundary prcssurc vanishes. We asume a smooth equation of slate for which UW density and the speed of sound remain psilive for vanishing pressure. PACS numten: 0230, 0420

Non-Static Spherically Symmetric Perfect Fluid Solutions
We investigate solutions of Einstein field equations for the nonstatic spherically symmetric perfect fluid case using different equations of state. The properties of an exact spherically symmetric perfect fluid solutions are obtained which contain shear. We obtain three different solutions out of these one turns out to be an incoherent dust solution and the other two are stiff matter solutions.
متن کاملEleven spherically symmetric constant density solutions with cosmological constant
Einstein’s field equations with cosmological constant are analysed for a static, spherically symmetric perfect fluid having constant density. Five new global solutions are described. One of these solutions has the Nariai solution joined on as an exterior field. Another solution describes a decreasing pressure model with exterior Schwarzschild-de Sitter spacetime having decreasing group orbits a...
متن کاملSome Static Isotropic Perfect Fluid Spheres in General Relativity
In the present article, a new class of solutions of Einstein field equations is investigated for a spherically symmetric space-time when the source of gravitation is a perfect fluid. All the solutions have been derived by making some suitable arrangements in the field equations. The solutions so obtained have been seen to describe Schwarzschild interior solutions. Most of the solutions are subj...
متن کاملGlobal Solutions to the Spherically Symmetric Compressible Navier-Stokes Equations with Density-Dependent Viscosity
We consider the exterior problem and the initial boundary value problem for the spherically symmetric isentropic compressible Navier-Stokes equations with density-dependent viscosity coefficient in this paper. For regular initial density, we show that there exists a unique global strong solution to the exterior problem or the initial boundary value problem, respectively. In particular, the stro...
متن کاملSymmetric Vacuum Einstein Field Equations
According to Birkhoff’s theorem the only spherically symmetric solution of the vacuum Einstein field equations is the Schwarzschild solution. Inspite of imposing asymptotically flatness and staticness as initial conditions we obtain that these equations have general solutions with the Schwarzschild metric as merely a special and simplest form of them. It is possible to have perfect and smooth m...
