Kantowski-Sachs String Cosmological Model with Bulk Viscosity and Time Dependent ? term in General Relativity

Shilpa Samdurkar

Abstract: We have studied a new solution of Einstein-s field equations for Kantowski-Sachs Model attached with cloud of string in the presence of bulk viscosity and time dependent cosmological term of the form. To get deterministic model of the universe, here we have imposed the condition that the shear scalar is proportional to expansion scalar. Some physical and geometrical properties of the models are discussed. We conclude that the universe model does not approach isotropy through the evolution of the universe.
