Özet:

 

Considering a spherically symmetric nonstatic cosmological flat model  of the Robertson-Walker universe, the problem of perfect fluid distribution   interacting with the gravitational field in the presence of a zero-rest-mass   scalar field and electromagnetic field in Brans-Dicke (B-D) theory has been   investigated. Exact solutions are obtained by using a general approach of   solving the partial differential equations and it has been observed that the   electromagnetic field cannot survive the cosmological flat model due to the   action caused by the presence of the zero-rest-mass scalar field, and the   isotropic pressure p turns out to be negative. The pressure and density are   found to be independent of time.
