Final Report Summary - HUBSYNC (Synchronization in heterogeneous Networks)
In most realistic networked systems where synchronization is relevant, strong synchronization may also be related to pathological activities such as epileptic seizures and social catastrophes in epidemic spreading. Recent experiments have revealed that various levels of synchronization are needed to avoid pathological activities and enable a system to have flexibility and robustness. Despite the growing interest in network dynamics, the present state of knowledge cannot explain the various levels of synchronization observed in real-life complex systems.
During our project we have developed a mathematical theory for the emergence of structured synchronisation in heterogeneous networks of interacting dynamical systems. Our results provide ways to understand how the underlying network connectivity can affect the overall dynamics. For example, our results show that in directed networks structural improvements can lead to functional failures. These results play a vital role towards the ultimate goal of understanding the emerging spontaneous collective motion in complex systems.
