Bianchi Type-V Cosmological Models with Viscous Fluid & Varying Ʌ

Abstract

Homogeneous and anisotropic Bianchi type-V cosmological models with time -varying have been investigated in presence of bulk viscosity. Cosmic matter is taken to obey a barotropic equation of state.  Some exact solutions of the Einstein field equations have been solved assuming the  Ʌ = α/R (where R is scale factor and α is constant).We find that corresponding solutions reflect the well-established features of the cosmology.
