LRS Bianchi Type V Cosmological Model With Variable G and 

Sanjay Kumar, A. Prasad

Abstract


In this paper space-time varying gravitational constant G(x, t) and cosmological constant L(x, t) are explicitly determined as G(t) and L(t) in an LRS Bianchi type V model filled with perfect fluid satisfying barotropic equation of state. Physically realistic solutions of Einstein’s field equations are obtained by assuming the condition 1). We observe that the corresponding models retain well established features of the standard cosmology, in addition expanding behaviours of the resulting model include late times accelerations in a particular situation.
