Abstract
- We study the homogeneous and anisotropic evolution of spacetime driven by perfect fluid with shear viscosity. We obtain exact solutions by considering the simplest form of the equation of state wherein the pressure and the shear stress are proportional to the energy density individually. The solutions represent Bianchi type-I cosmology of which the special case becomes Bianchi type-VII. We find that the initial singularity can be removed only for the Bianchi type-VII.<br />Comment: 23 pages, 5 captioned figures. arXiv admin note: text overlap with arXiv:2209.12544
