Scientific paper

We show that the dynamical behavior of the scale factor in FRW cosmologies with equation of state p = (γ - 1)ρ is formally equivalent to a classical particle under the action of a homogeneous potential V(q) = αqn, where α and n are constants. The relations γ(n) and ɛ(E,n), where ɛ is the curvature parameter and E is the total energy of the test particle, are established. It is shown that the same approach can be generalized to include a nonvanishing cosmological constant as well as to describe viscous models. A comparison is made between the Lagrangian and general relativistic possibilities.
