Abstract
A dynamical system with Robertson-Walker symmetries and the equation of the statep=γ∈, 0≤γ≤1, considered both as a conservative and nonconservative system, is studied with respect to its structural stability properties. Different cases are shown and analyzed on the phase space (x=R D, y=x).
