v 1 4 A ug 1 99 3 Dust - Radiation Universes : Stability Analysis

Abstract

In this paper we consider flat and open universe models containing a mixture of cold matter (dust) and radiation interacting only through gravity, with the aim of studying their stability with respect to linear scalar perturbations. To this end we consider the perturbed universe as a dynamical system, described by coupled differential equations for a gauge… (More)
