2 may provide an explanation why complexity arises in nature. It states that in a complex system a goal dynamics at the edge of chaos can be most easily imposed. Again, in analogy, a weakly singular system may be controlled with the smallest driving effort. There is a tendency of the dynamics of evolving complex systems itself to leave a highly complex state and return to less complex states (simplification paradigm). We discuss the different paradigms and the special status of states at the edge of chaos in the outlook.

There may be experimental systems where this classification does not fit. Given that the dynamics of a dissipative system collapses rapidly onto one of attractors of the low-dimensional model, several questions arise: (i) Is the ALM smooth? Eq. (6) contains a third order nonlinearity whereas the original equation Eq. (2) was second order. A successive elimination of more and more governed variables in a high dimensional systems might produce higher and higher nonlinearities and converge to a non-smooth flow vector field.

In the lower deck (width 0(E 5 )), the flow is viscous and the suction provides a (downward) displacement of the flow which is transmitted through the middle deck (width 0(E 4 )), in which the flow is essentially the Blasius flow plus an inviscid perturbation due to suction, into the upper deck (width 0(E 3 )) which protrudes into the outer flow. This displacement acts to adjust the upper-deck pressure, which in turn feeds back into the lower deck, and a local interaction process is set up - see figure 5.
