Abstract

We study quasi-spherical Szekeres space–time (which possess no killing vectors) for perfect fluid, matter with tangential stress only and matter with anisotropic pressure respectively. In the first two cases cosmological solutions have been obtained and their asymptotic behavior have been examined while for anisotropic pressure, gravitational collapse has been studied and the role of the pressure has been discussed.
