Scalar fields in an anisotropic closed universe

Astrophysics 2009-10-31 v1

Abstract

We study in this article a class of homogeneous, but anisotropic cosmological models in which shear viscosity is included. Within the matter content we consider a component (the quintessence component) determined by the barotropic equations of state, p=αρp=\alpha \rho, with α<0\alpha < 0. We establish conditions under which a closed axisymmetrical cosmological model may look flat al low redshift.
