Abstract

In this paper, we have examined non-shearing locally rotationally symmetric Bianchi Type - III String cosmological models in the presence of bulk viscosity and variable cosmological term Λ. To obtain a determine model of the universe, we have assumed that the coefficient of the viscosity ζ is inversely proportional to the expansion scalar θ and Λ is proportional to the Hubble parameter H. The physical and geometrical behaviors of the models are also discussed.
