چکیده
Some exact solutions for the Einstein eld equations corresponding to inhomogeneous G2 cosmologies with an exponential-potential scalar eld which generalize solutions obtained previously are considered. Several particular cases are studied and the properties related to generalized in ation and asymptotic behaviour of the models are discussed.

Asymptotic behaviour of a class of inhomogeneous scalar field cosmologies
The asymptotic behaviour of a class of inhomogeneous scalar field cosmologies with a Liouville type of potential is studied. We define a set of new variables for which the phase space of the system of Einstein equations is bounded. This allows us to perform a complete analysis of the evolution of these cosmologies. We also discuss the extension of the cosmic no-hair theorem.
متن کاملOn Average Properties of Inhomogeneous Fluids in General Relativity: Perfect Fluid Cosmologies
For general relativistic spacetimes filled with an irrotational perfect fluid a generalized form of Friedmann’s equations governing the expansion factor of spatially averaged portions of inhomogeneous cosmologies is derived. The averaging problem for scalar quantities is condensed into the problem of finding an ‘effective equation of state’ including kinematical as well as dynamical ‘backreacti...
متن کاملOn the Evolution of a Large Class of Inhomogeneous Scalar Field Cosmologies
The asymptotic behaviour of a family of inhomogeneous scalar field cosmologies with exponential potential V = Λe is studied. By introducing new variables we can perform an almost complete analysis of the evolution of these cosmologies. Unlike the homogeneous case (Bianchi type solutions), when k2 < 2 the models do not isotropize due to the presence of the inhomogeneities.

متن کاملReinterpreting Quintessential Dark Energy through Averaged Inhomogeneous Cosmologies
Regionally averaged relativistic cosmologies have recently been considered as a possible explanation for the apparent late time acceleration of the Universe. This contribution reports on a mean field description of the backreaction in terms of a minimally coupled regionally homogeneous scalar field evolving in a potential, then giving a physical origin to the various phenomenological scalar fie...
