Abstract
The paper deals with the weakly non-linear temporal stability of the mean flow of a turbulent boundary layer. The linear approximation first studied by Stephan had led to weakly damped modes. Here the amplitude equations are derived, the non linearities arising to second order due to the existence of three wave resonance. Some exact solutions of the amplitude equations are examined: they break down after a finite time, yielding an amplification mechanism.
