Conclusion
We present in this module some definition of the energy cascade which characterizes the multifractal models and allows to generate an intermittent fields. These fields have several fractal dimension corresponding to an infinite hierarchy of singularities. They are obtained according the multufractal cascade process with the respect of scale invariance propriety.
We showed that, there exist several model, from the simplest one
-model which can be consider as powerful pedagogic model to much complex one, as the GSI model. There exist another type of cascade which is the continuous cascade , and we will give a complete presentation in the model Continuous Cascade. It is much more realistic model.
