Analyse TOpologique et MOdélisation de SYstčmes Dynamiques

ATOMOSYD is an acronym to designate the approach we develop to investigate dynamical systems. We are concerned by the topological analysis, that is, a global approach of the phase portrait, and global modelling which corresponds to the possibility to obtain a set of differential equations from measurements.

This web site is devoted to any features related to the nonlinear dynamical systems theory. Of course, our research activities can be found in section A research group but other topics are also considered as

- Dynamical systems

- Algorithms for investigating data

- Data sets useful for applying new tools

We are working for leaving this web site alive. If you have any remark, please, tell us

Chaos : from theory to applications
A focus issue to be published in Chaos

We are pleased to announce the forthcoming publication of a new Focus Issue entitled “Chaos : From Theory to Applications” in Chaos : An Interdisciplinary Journal of Nonlinear Science to celebrate the 80th birthday of Otto E. Rössler.

Otto submitted his first paper on chaos in 1976. The Rössler system quickly became one of the prototypes on which the paradigm of chaos theory is constructed. He also introduced hyperchaos and suggested a classification of chaotic attractors. Otto E. Rössler investigated applications of chaos in various fields : chemistry, heart rhythm, biology, electronics, astrophysics, fluid mechanics

In order to celebrate his contribution to chaos theory, and in honor of his 80th birthday, this forthcoming focus issue in Chaos is devoted to showing how chaotic behaviors help to understand the reality of the world in its complexity. Contributions should try to show how the concepts of state space, attractor, first-return maps Poincaré sections, bifurcations, etc. allow for better views of the possible dynamics produced by simple as well as complex systems. Contributions can be either theoretical, numerical or experimental.

For those who met Otto E. Rössler and who would have particular recollections, we offer the opportunity to contribute to a co-authored paper in which each contributor will write about one half or one page (possibly with one picture or one figure) for providing to the community how Otto was perceived along his career. For this type of contribution, please contact Christophe Letellier.

This Focus Issue is scheduled for publication in December 2020. All submitted articles should conform to the Chaos author guidelines. Please be sure to write a lead paragraph – see guidelines for more detail. Papers will be published immediately after acceptance and will publish online in the journal and in a virtual collection dedicated to this Focus Issue.

Please let us know if you intend to contribute to this Focus Issue by FILLING OUT this survey by JANUARY 18, 2020. If so, you will receive notification when we are open for submissions and we look forward to receiving your submission by AUGUST 21, 2020. Your manuscript will be reviewed within 4-6 weeks of submission.

We hope that you will be able to contribute to this exciting Focus Issue in Chaos.

With warm regards,

Guest editors :
Christophe Letellier (Rouen Normandie University, France)
Sylvain Mangiarotti (Centre d’Etudes Spatiales de la Biosphčre, Toulouse, France)
Lars Folke Olsen (University of Southern Denmark, Odense )
