On the Anisotropic Big Bang Cosmology With A General Non-Linear EoS

preprint2010arXivOpen access

Abstract

We study the anisotropic Big Bang cosmology for a general non-linear equation of state (EoS) in standard general relativity cosmology in early times. According to brane world cosmology and loop quantum gravity which introduce a quadratic term in the energy density, we study a non-linear EoS with a general nonlinear term in the energy density. We show that this general non-linear term isotropize the universe at early times. And also, we find out this model has a phantom like behavior for special case.
