Bianchi Type-I Bulk Viscous Cosmological Models with Constant Deceleration Parameter

Abstract

Einstein field equation with variable cosmological term Λ are cosidered on the presence of viscous fluid for Bianchi type–I cosmological models by assuming that deceleration parameter is constant. We found that cosmological term Λ is a decreasing function of time. Physical  and kinematical  behaviour has been also discussed.
