Otto Hahn junior research group of the MPS at the MPI-PKS

Dynamical systems and Social Dynamics

home members research publications contact

This page/group was active between January 2011 and August 2016x

At the Otto-Hahn group Dynamical systems and social dynamics we are inspired and guided by the basic message of complexity theory that complex behavior often emerges from simple rules. In our case we focus on dynamical-systems models that lead to complex temporal behavior, usually due to the interplay between nonlinear-deterministic and stochastic processes. We apply these models to understand paradigmatic dynamical systems in Physics (e.g., chaotic billiards) and to explain the statistical properties of collective human activities (e.g., user activities in the Internet). Concrete examples of problems can be found in the research section, in our list of publications, and in the webpage of the members. You can also contact us for more information on our research and for possibilities of joining the group.
