Essential in synergetics is the order-parameter concept which was originally introduced in the [[Ginzburg–Landau theory]] in order to describe [[phase transition|phase-transitions]] in thermodynamics. The order parameter concept is generalized by Haken to the "enslaving-principle" saying that the dynamics of fast-relaxing (stable) modes is completely determined by the 'slow' dynamics of as a rule only a few 'order-parameters' (unstable modes). The order parameters can be interpreted as the amplitudes of the unstable modes determining the macroscopic pattern. | Essential in synergetics is the order-parameter concept which was originally introduced in the [[Ginzburg–Landau theory]] in order to describe [[phase transition|phase-transitions]] in thermodynamics.
