Analytical solutions for cosmological perturbations in a one-component universe with shear stress

General Relativity and Quantum Cosmology 2015-05-22 v2

Abstract

We construct explicit solutions for scalar, vector and tensor perturbations in a less known setting, a flat universe filled by an isotropic elastic solid with pressure and shear modulus proportional to energy density. The solutions generalize the well known formulas for cosmological perturbations in a universe filled by ideal fluid.
