We add now an important element to our discussion, namely a parameter. The parameter will always be called μ, and we want to study maps f, depending on μ. Before doing this, we illustrate in a physical example how one should think of μ and of the map. The example how one should think of μ and of the map. The example we choose is the Reyleigh-Bénard experiment, as performed by Libchaber-Maurer . The setup is as follows. The physical system is a small receptacle containing a liquid (liquid Helium). Through some device, one can fix the temperature difference between the top and the bottom of the receptacle. This temperature difference is the control parameter μ for this system.
