Thermodynamic Aspects of the Evolution of Self-Organized Systems

The school from Brussels have found that for the systems maintained far from thermodynamic equilibrium and when the kinetic laws are suitably nonlinear, the excess entropy production, δxP, becomes negative for t > to. In this case, the nonequilibrium steady state becomes unstable and sometimes, when the internal structure permits, the system executes limit cycle oscillations [1–3].
