Abstract

Considering a spherically-symmetric non-static cosmological flat model of Robertson-Walker universe we have investigated the problem of perfect fluid distribution interacting with the gravitational field in presence of massive scalar field and electromagnetic field in B-D theory. Exact solutions have been obtained by using a general approach of solving the partial differential equations and it has been observed that the electromagnetic field cannot survive for the cosmological flat model due to the influence caused by the presence of massive scalar field.
