Bulk Viscous Bianchi Type I Barotropic Fluid Cosmological Model with Varying Λ and Functional Relation on Hubble Parameter

摘要

Bianchi Type I bulk viscous barotropic fluid cosmological with varying Λ is investigated. We have also assumed a functional relation on Hubble parameter as H(R)=a(R −n +1), n1, a0, H the Hubble constant, R being scale factor and $H = dot{R}/R$ . The physical and geometrical aspects of the model related with astronomical observations are discussed.
