Abstract :
The present study deals with a spatially homogeneous and anisotropic Bianchi type VI0 space-time in the presence of string of clouds and perfect fluid distribution within the context of gravity. The analytic relation and the hybrid exponential form of the average scale factor have been considered to obtain the exact solutions of highly non-linear field equations. Some physical and kinematical parameters of the constructed model along with the behavior of the equation of state parameter for string fluid are discussed and presented graphically.

Key-Words / Index Term :
Bianchi-type VI0 space-time, Cosmic String, Perfect Fluid, Gravity.
