Abstract
A set of “dimensionless” equations of state is used to show that the Einstein field equations governing a class of Bianchi VI0 imperfect fluid cosmologies reduce to a plane-autonomous system of equations. The qualitative behavior of the underlying cosmological models is obtained by investigating this plane-autonomous system.
