摘要

FRW models of universe in the presence of viscous fluid are investigated in the cosmological theory based on Lyra's Manifold. By considering the deceleration parameter to be a variable and the viscosity coefficient of bulk viscous fluid to be a constant, exacts solutions have been obtained from which three forms of model of the universe are derived. The physical properties of the models are also investigated.
