In recent years experiments on fluids have demonstrated that the onset of
weak turbulence follows well-defined bifurcation routes. Three main sce-
narios have been identified: a cascade of period doubling, intermittency,
and quasiperiodic routes. It is all related to the three possible ways a limit
cycle loses its stability. The generality of the phenomenon is such that it
can be observed in numerous physical systems, such as a pendulum,
electronic circuits, and wave phenomena. In the following we give a few
general references, far from being exhaustive.
