Structure and Dynamics of Social Networks

Centre of Excellence in Computational Complex Systems Research


Discovering the structural and dynamical properties of social networks is an inspiring topic of complex networks research that has received much attention in recent years. Although the social behaviour of every individual human being is different, dynamic processes such as activating and deactivating social ties lead to certain "universal" aspects of social network structures, such as the "small-world" property and the existence of communities with dense internal links and weaker links between them. These structural properties also have effects on dynamic phenomena taking place on social networks, such as diffusion and transfer of information. Using real-world or simulated networks as "lattices", fundamental characteristics of these types of processes can be investigated with computer simulations.

This research is mainly conducted by the Complex Networks & Agent-Based Models research group.
