Bianchi Type-II Inflationary Universe with Massive String Source in General Relativity

D. R. K. Reddy


This study is about an inflationary cosmological model in the presence of scalar field with a  flat potential  and a massive string source in general relativity in the framework of  locally rotational symmetric(LRS) Bianchi type-II space-time. An exact solution of the field equations is determined using the fact that scalar expansion is proportional to shear scalar and a hybrid expansion for the average scale factor of the model. We have determined the scalar field, energy density  and tension density of the string in the model. We find all the dynamical parameters of the model and discuss their physical importance.
