Abstract

Bianchi type \({VI}_0\) viscous fluid cosmological models satisfying barotropic equation of state with varying cosmological term \(\varLambda \) are investigated. We have examined a cosmological scenario proposing a constant ratio between shear \(\sigma \) and volume expansion \(\theta \) in the background of homogeneous, anisotropic Bianchi type \({VI}_0\) space–time. The cosmological term \(\varLambda \) is found to be decreasing function of time which is supported by results from recent supernovae Ia observations. The model remains anisotropic throughout the evolution. Cosmological consequences of these models have been discussed.
