| Abstract: | ![]()
A dynamical system with Robertson-Walker symmetries and the equation of the statep=  , 0 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=RD, y=x). |
