Abstract
We study the homogeneous and anisotropic evolution of Bianchi type-Ispacetime driven by perfect fluid with shear viscosity. We obtain exactsolutions by considering the simplest form of the equation of state whereinthe pressure and the shear stress are proportional to the energy densityindividually. A special case of our general solutions represent Bianchitype-VII cosmology. We analyse the singularity structure of the solutionsand its connection with various energy conditions. We find that theinitial singularity can be removed only for the Bianchi type-VII. We alsoanalyse the late-time behaviour of the solutions and find that, comparedto the usual Friedmann universe, the spacetime expands less rapidly andthe energy density drops faster.
