Abstract

In this paper we have investigated the problems on physical distributions involving the Newton’s gravitational constant G and cosmological constant L which is considered varying as H2 .The field equations and their solutions for perfect fluid in Robertson-Walker universe for all the values of scale factor are discussed and we find the exact solutions satisfying the lawL¥t 2 .
