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
