Project 01

Evolution from small to large networks, their spectrum and related bifurcation scenarios

About the project:

Real world systems can be considered as networks consisting of many interacting elements. Recent studies show that the network structure can have dramatic influences on the dynamical properties of complex systems. This project deals with the dynamics of complex networks.


  • Study of the dynamical properties of networks, which are obtained by adding new connections to a regular lattice
  • Investigation of composed networks, where few of the regular sub-networks are coupled
  • Discovering the bifurcation scenarios in the above mentioned systems
  • Applications of the results to the networks used in climate modeling, as well as to neuronal models
