Dynamical Systems can be considered, at present, as a way to describe evolution problems with respect to time, let them be given by ordinary or partial differential equations or by discrete transformations. Both the qualitative and the quantitative aspects of the systems fall in this study. A key idea is the consideration of that evolution in the phase space or, better, in the phase-and-parameter space, to take into account the dependence of the system with respect to parameters (bifurcations).

Researchers in the Barcelona area, and more generally in Catalonia, group themselves into smaller research groups, following not only academic but also administrative criteria, like location or research grants.
