Symmetry-based study and dynamics of casual bulk viscous matter-dominated universe

Abstract The dynamics of cosmological expansion is studied for a spatially flat matter-dominated universe filled with barotropic casual bulk viscous fluid. The evolution equation for the Hubble parameter is derived using Friedmann equations and conservation law for the viscous fluid, in which the vi...
