Viscosity effects in (1 + 1)-dimensional cosmologies
We investigate the behaviour of the solutions to the gravitational (1 + 1)-dimensional equations with a viscous fluid source in the case of a Robertson-Walker metric. In our model the bulk viscosity coefficient is related to the energy density as ξ = αρm and we also take into account the effects of...
