Abstract

We perform a global analysis of curved Friedmann–Robertson–Walker cosmologies in the presence of a viscous ﬂuid. The ﬂuid’s bulk viscosity is governed by a frst order theory recently proposed in Disconzi et al (2015 Phys. Rev. D 91 043532), and the analysis is carried out in a compactifed parameter space with dimensionless coordinates. We provide stability properties, cosmological interpretation and thermodynamic features of the critical points.
