Eigen diagram

Fig. 9.3 Entropy-time diagram of an evolution process. If a negative fluctuation of the internal entropy production o occurs in a system, the controlling stationary state is terminated. An instability occurs, starting from which a new stable state is taken up. The change in the internal entropy is always negative (5Si < 0). The new stationary state has a lower entropy, i.e., the order of the system is increased (Eigen, 1971a, b)...

Systems with more than two independent variables can be analyzed in a similar way. The stable points in the phase diagram for such systems also are classified on the basis of characteristic solutions of the relevant eigen value equation. Lately, the positions of stable and attracting states of the dynamic system have been referred to as attractors. ...
