Study of the Quasi-isotropic Solution near the Cosmological Singularity in Presence of Bulk-Viscosity
We analyze the dynamical behavior of a quasi-isotropic Universe in the presence of a cosmological fluid endowed with bulk viscosity. We express the viscosity coefficient as a power-law of the fluid energy density: ζ = ζ0 ǫ . Then we fix s = 1/2 as the only case in which viscosity plays a significant role in the singularity physics but does not dominate the Universe dynamics (as requested by its...

We analyze the dynamical behavior of a quasi-isotropic Universe in the presence of a cosmological fluid endowed with bulk viscosity. We express the viscosity coefficient as a power-law of the fluid energy density: ζ = ζ0 ǫs. Then we fix s = 1/2 as the only case in which viscosity plays a significant role in the singularity physics but does not dominate the Universe dynamics (as requested by its...
متن کاملGeneral properties of cosmological models with an Isotropic Singularity
Much of the published work regarding the Isotropic Singularity is performed under the assumption that the matter source for the cosmological model is a barotropic perfect fluid, or even a perfect fluid with a γ-law equation of state. There are, however, some general properties of cosmological models which admit an Isotropic Singularity, irrespective of the matter source. In particular, we show ...
متن کاملIsotropic Cosmological Singularities Ii. the Einstein-vlasov System
We consider the conformal Einstein equations for massless colli-sionless gas cosmologies which admit an isotropic singularity. After developing the general theory, we restrict to spatially-homogeneous cosmologies. We show that the Cauchy problem for these equations is well-posed with data consisting of the limiting particle distribution function at the singularity.
متن کاملOn the Quasi-Isotropic Inflationary Solution
In this paper we find a solution for a quasi-isotropic inflationary Universe which allows to introduce in the problem a certain degree of inhomogeneity. We consider a model which generalizes the (flat) FRW one by introducing a first order inhomogeneous term, whose dynamics is induced by an effective cosmological constant. The 3-metric tensor is constituted by a dominant term, corresponding to a...
