“Relativistic Viscous Hydrodynamics” by Denis George Mih (Queen Mary University of London)

We analyse the dynamics of the Friedmann-Robertson-Walker and Bianchi I cosmologies when considering a viscous fluid. By examining the role of the regulator introduced by Lichnerowicz to avoid the causality issue in Eckart theory, we formulate a dynamical system which we solve analytically in both cosmological models.
