• RELATIVISTIC COSMOLOGICAL MASS MODEL

Abstract

In this paper, the problem of spherically symmetric homogeneous space time with perfect fluid and viscous fluid distribution are considered separately in Einstein theory alongwith the cosmological term. In order to obtain the exact solution, we have assumed the barotropic equation of state p =, -1 . It is observed that fluid distribution generates isotropic false vacuum model when  = -1 and the solution becomes singular at r = -b. The cream of this paper is the viscous fluid distribution for the space time yields the case of perfect fluid distribution without imposing any condition and restriction
