Aims and Scope

The theory of dynamical systems relates in an obvious way to the two basic objectives which are common to many Sciences : Explanation of past or present natural phenomena and prediction of the future behavior of both natural and artificial systems.

In many cases, the solution to these problems relies on a theoretical study of asymptotic behavior of trajectories or sets of trajectories of some dynamical system as time becomes infinite. The emergence of a stable pattern corresponding to a "shape" is associated to convergence to some kind of steady state. On the other hand complicated and unstable patterns can be interpreted as a form of chaos which is realized in the mathematical models in the form of fractal attracting sets.

Related to the duality explanation vs prediction we also find the duality analysis vs synthesis : from the observation of natural systems, how to create an artificial one allowing to pass from a given "natural "state to a different wanted state. This is, in particular, the object of (exact or approximate) control theory. Ideally one wants to make the transition at a minimal energy expense, and this is the object of optimal control theory.

One objective of this meeting is to bring together a number of well-known specialists of various aspects of dynamical systems, ranging from modelization of natural systems to the synthesis of processes designed to achieve a desired technological goal. In the same meeting we welcome young bright researchers which shall both explain us the state of the art in their specialized field of research and confront their expertise with the more global vision of elder researchers, especially those which operate at the interface of basic abstract theory and application to real Science and Technology.
