Barotropic Cosmological Models with Varying Gravitational Constant in Hoyle Narlikar’s Creation Field Theory of Gravitation

Abstract

Plane symmetric and LRS Bianchi type – V cosmological models have been studied with varying gravitational constant G in Hoyle Narlikar’s creation field theory of gravitation for the barotropic fluid distribution. The solution of the field equations have been obtained by assuming that G=B^m, where B is scale factor and m is a constant, Also, the physical properties of the model are studied.
