Generation of LRS Bianchi type I universes filled with perfect fluids

Abstract

A generating technique is presented which converts known LRS Bianchi type I models into new models of the same type. Starting from the general Kasner solutions new classes of models are obtained which add to the rare perfect-fluid solutions not satisfying the equation of state. The physical and kinematical properties of cosmological models are studied. © 1989 Plenum Publishing Corporation.
