Conformally Flat Spherically Symmetric Cosmological Models-Revisited
arXiv:gr-qc/0211008
Abstract
Conformally flat spherically symmetric cosmological models representing a charged perfect fluid as well as a bulk viscous fluid distribution have been obtained. The cosmological constant Λis found positive and is a decreasing function of time which is consistent with the recent supernovae observations. The physical and geometrical properties of the models are discussed.
